Never heard Jorge Ben's debut but he seems pretty consistent. My favorites of his are "s/t ('69)", "Tabua De Esmeralda", "Negro E Lindo" and "Ben".
The list does have a lot of my favorites on it and a lot of cool obscure picks but the order is all ####ed up (not that that really matters). These are the albums that seem most interesting from the Pitchfork list (that I haven't heard):
BBC Radiophonic Workshop - s/t
Patty Waters - Sings
Steve Reich - New Sounds in Electronic Music (been meaning to check this out for awhile)
