I Am the Blues, Willie Dixon
-- Willie Dixon is indeed the blues, but I think this demonstrates that prolific songwriters are often songwriters because they lack a singing voice. Dixon's voice isn't bad per se, it's just no match for the guys who sang the songs he wrote. Still, this is considered one of the heavyweight blues albums of the decade and features a lot of material that was covered by Led Zepplin, Cream, the Doors, the Stones and so on, which means that you should probably listen to it.
Indianola Mississippi Seeds, B.B. King
-- Solid blues by B.B. King. King isn't my favourite Blues musician by any stretch but I could imagine digging this if it was on in the background of a Blues bar or something.
Les stances a Sophie, Art Ensemble of Chicago
-- This was a film soundtrack that became a rather legendary piece of avant-garde jazz. The opening track is amazing and perhaps my favourite song of 1970. The rest of the album was far more challenging for a jazz dabbler such as myself.
Deaf Dumb Blind (Summun Bukmun Umyun), Pharoah Sanders
-- Probably my favourite jazz album so far. Only two tracks -- the first has a rhythm and R&B influence which obviously I dig and the second is an old spiritual. This poll is the first time for me to listen to free jazz so I don't know what's going on, but I liked this album.
