Alors, la branche vieillesse avec les retraites c'est fait, l'Assurance Maladie c'est toujours en cours, la Famille c'est bien bordé par le maxi-flicage de la CAF, le chômage c'est bon ça repart au pot commun. Ca y est, on en a fini avec la Sécu. 😊

Le droit de grève c'est en cours, la liberté d'expression tu te la roules en cône et tu la fumeras avec un dispositif sonore portatif dans l'autre main.
On s'attaque enfin à la fonction publique, prochain move du gouvernement : Le travail pour les enfants à partir de 8 ans. Je crois qu'il reste plus que ça avant le retour au 19è siècle.(mais avec des IA, des chats mignons et des emojis sympa 🥰 )

Working on a poster for the upcoming coffee corner in our kitchen. The poster is heavily inspired by one I found online, but I decided to make my own because the original didn't have all the drinks I wanted, it didn't show measurements, and finally, it's an opportunity to exercise my drawing skills 😄

@simonbs @duclearc Unfortunately, there doesn't look like there is enough space to print “90 ml Expresso Water”, with no line break between Expresso and Water.

@deevybee
Not just about mental health: it's also about the moral ground of academia.

« Most people going into universities had at the start an ethical sense of their future, a vocation, something that wasn’t just mechanical but which was somehow simply right. The university must be just such a moral place, or it is nothing. »

Juge pas mon genre: En France, chaque année, des centaines de personnes trans doivent encore passer par les tribunaux pour changer la mention du sexe qui apparaît sur leurs papiers d’identité.

Il faut mettre en place un changement de sexe à l’état civil qui soit déjudiciarisé, libre et gratuit pour toutes les personnes trans, et qui puisse se faire sur simple demande.

@lelibreedu
Bonjour, j'ai une question sur les ordinateurs confiés aux lycéen·nes: il n'y a dessus quasi pas de logiciel pour taper du code, juste le bloc notes et un autre similaire. N'y aurait-il pas intérêt à mettre quelque chose de plus avancé, même vscode, d'autant plus qu'il est apparemment impossible/interdit d'installer quoi que ce soit soi-même.

There was a guy named Maxwell,
who was born on that day, 100 years ago,
even if his birth certificate doesn't say so.
His second name was Lemuel.
Whatever — everybody calls him Max.
Let's embark for a 100 days celebration
with Max Roach, here on Mastodon.

  1. Perdido

A Live in Berlin album by the same quartet, recorded in 1984. The song is a bop classic, a composition of Juan Tizol, the famous trombone player in Duke Ellington's band, and also a composer of great songs, of that one, as well as of Caravan.

Nevertheless, the style in which the musicians explore the song is definitely different from the early be bop era. While bass (Tyrone Brown) and drums (Max Roach) provide a consistent and regular groove, trumpet (Cecil Bridgewater) and saxophone (Odean Pope — but the cover says Odeon…) propose kind of a deconstructed version of the classic theme. The second lines are not just here as an ornament, but more as if there were two voices, sometimes in par, sometimes dissonant.

The bass solo is excellent, and when it's time for a drum solo, it is amazing how Roach uses silence to create expectation.

  1. Mr Seven

One more piece by M'Boom, from their third album Collage.

It is called Mr Seven because it is based on an infectious 7/8 groove—the composer is Warren Smith.

Max Roach plays vibraphone, Kenyatte Abdur-Rahman is on bass drum and xylophone,
Eddie Allen on bell tree, cabasa, cymbal, Eli Fountain on bells, drum and snare, Ray Mantilla on bells, Joe Chambers on marimba, Fred King on timpani, Roy Brooks on tom tom, Freddie Waits and Warren Smith play “various percussion”!

Will you dance?

  1. Survivors

Recorded in 1984, this surprising album “with string quartet” — Christopher Finckel on cello, Louise Schulman on viola, Guillermo Figueroa and Donald Bauch on violin — is a kind of duet for the string quartet seems to sing with one voice, the other being Max Roach's drums. (The other tracks from that album are solo pieces.)

  1. Sis

In 1984, Max Roach recorded two albums with a string quartet, a double quartet this time: his own jazz quartet (Cecil Bridgewater, trumpet; Odean Pope, tenor saxophone; Tyrone Brown, electric bass), and the Uptown String Quartet consisting of Cecelia Hobbs and John McLaughlin Williams, violin; Maxine Roach (his daughter !), viola; Eileen Folsson, cello.

It seems to me that the writing is more elaborate, that he uses the string quartet in a more structured way that allows the voices of the four strings to develop independently.
In any case, this melody, Sis, a composition of Odean Pope, is a beautiful one.

  1. Bird says

From the same double quartet album as yesterday, this is a composition by the trumpet player Cecil Bridgewater that pays homage to the music of Charlie Parker — Bird. In the string arrangement, you can recognize a number of compositions of Parker. (I'm impressed by the vigor of the bass player who plays these quarter notes at high speed — 240bpm — for more than 10 minutes…) After the sax chorus, the string quartet is offered arrangements of Parker songs, and then follows the finale — a drum/percussion chorus — where, once again, the melodic drumming of Max Roach allows to recognize some pieces of Parker.

  1. Ghost Dance

This track is taken from a two part recording. The first one is a 50 minute suite with the New Orchestra of Boston,
and the second one is a shorter song with The So What Brass Quintet — Marshall Sealy on french horn,
Steve Turre on trombone, Cecil Bridgewater and Frank Gordon on trumpet, and Robert Stewart on tuba.
The absence of harmonic instruments — no piano, no bass — makes that theme a rhythmic feast.

  1. Salt Peanuts

The last recordings of Max Roach contain two remarkable duet concerts, and tonight's track is taken from one with Dizzy Gillespie on trumpet. It is incredible how both musicians take this classic song as a joyful playground.

From the recording date, 23 March 1989, and the place it was recorded at — Maison de la culture de Saint Denis — I suppose that this concert was part of the Banlieues bleues program that, each spring, proposes concerts of that quality all over the Seine-Saint-Denis. (Neuf-Trois, as people say colloquially.)

(YouTube only proposes the full concert; the link starts at the right time.)

  1. Salt Peanuts

Max Roach had already recorded that tune, more than 35 years before, in the memorable 1953 concert at the Toronto Massey Hall. Charlie Parker was on saxophone, Charles Mingus on bass, Bud Powell on piano.

Enjoy these salt peanuts!

  1. Flirtations

The other great concert I was alluding to a few days ago happened in 1995 on the occasion of Mal Waldron's 70th birthday.

The concert starts with this free improvisation between the two masters.

  1. Soul Eyes

Same concert, a ballad composed by the pianist Mal Waldron to the intention of John Coltrane who recorded it in March 1957. In this version, Mal Waldron starts alone, and Max Roach joins him on brushes to end on sticks at the end of the tune. Mal Waldron has written lyrics, which Jeanne Lee rendered magnificently.

A soul, I'm told
Can be both hot and cold
So how is one to know
Which way to go?
