Believe it or not one of the best rock / music interviewers out there is none other than newsman Dan Rather with his The Big Interview series on AXS TV; I believe there are nine seasons out and if you can get past the fact that AXS TV seems to be run by teenagers (commercial breaks right in the middle of a sentence, etc) you will be richly rewarded with the substance of the interviews https://www.axs.tv/channel/the-big-interview-with-dan-rather/
