LaVerne Baker - "Saved." Great gospel track from who-knows-where.
Lawndale - Beyond Barbeque (1986). This is the woolly and heavily stoned work of a surf band that was on SST back in the day. Having recently finished Pynchon's Inherent Vice, with its many references to pyschedelic surf bands, I suspect Lawndale would be a favorite of Mr. Pynchon's.
Leadbelly - King of the 12-String Guitar (1935). There's better Leadbelly collections out there, but this one is okay. Not many of his best songs, though, and that's a shame for my only Leadbelly album.
