My latest is Tom Waits' "Orphans" and astounding Mexican guitar duo Rodrigo y Gabriela.
Waits started out on a compilation disk but wrote new songs and re-recorded old ones. He ended up with 3 cds, 56 songs, around 30 of which are new. Divided up among Brawlers, Bawlers and Bastards, each cd has a distinct sound and style, with Waits generally weird, outsider attitude and his strange roaring, grunting voice. A tour-de-force strait from the bar at the edge of the trailer park.
Rodrigo y gabriela are true virtuosos of accoustic finger picking. With no vocals, but but abundant guitar skills, they pick, strum and use their guitars as percussion to create a unique layered sound.
