I'd like to suggest Spotify have these recordings available for everyone to hear. I'm surprised some aren't in Spotify yet.
1) Captain Beefheart & His Magic Band - "Trout Mask Replica"
2) Rollins Band - Their Whole Discography
3) Henry Rollins - His Whole Discography
4) Suede - Their '90s recordings and the rest that aren't in Spotify
5) Various Artists - "The Beat Generation" [Box Set]
6) Various Artists - "Rhapsodies in Black: Music and Words from the Harlem Renaissance" [Box Set]
Anyone who'd like to add their suggestions in the thread feel free to do so.
