there is a podcast series you may like. my friend david grisman and i have been doing a series of podcasts discussing his wonderful music. he has a label called acoustic disc, with over 90 releases on it of non-mainstream stuff. we go through a record at a time talking about how each came about. it’s fun to talk to him about tape machines and consoles and mics and stuff, as well as how the compositional/conceptual side was put together. this is ongoing so we are working on more.
There are several episodes but certainly two of interest to this group will be "Garcia Grisman" and "Not For Kids Only."
