Soul Garage rules, dormant though it is. There's a ton of great stuff, all obscure, most only known to collectors. It's like finding that bag of old thrift store finds in the back of the closet and being reminded why you kept them. The descriptions at Soul Garage are in German but when you hear a song you like you can copy and paste and translate the text online.
These two have been here before, but you don't know that. The first is Dee Dee Warwick's original version of "You're No Good", the song that was a hit later for Linda Ronstadt. Produced by Leiber and Stoller, with a short and simple semi-fuzzed out guitar solo. The other song is Oscar Brown Jr's version "Work Song", because bongos.
