Yeah, part of the fun of "The Lost Tapes" is picking out embryonic versions of later songs. Cool how they play with "Spoon"'s rhythm and I actually find "Dead Pigeon Suite" way more interesting than "Vitamin C" and wish they had put that on "Ege Bamyashi" instead.
The songwriting on "Berlin" is already pretty hit or miss and the production just kills it more me. ####in Ezrin. Aside from "Transformer", the main solo Lou albums I recommend are "Coney Island Baby" (understated and mature but still with tongue in cheek and great tunes) and "Sally Can't Dance" (ridiculously underrated because it's silly as hell but it's Lou's obviously having a lot of drug fueled fun and I find the fun to be infectious). Also, all big Lou fans should pick up the live "American Poet" album. Recorded in '72 on the "Transformer" tour. Guitarist and drummer can both overplay at times but generally Lou and the band are in fine form. Mops the floor with "Rock & Roll Animal".
Glad yer diggin "Sowiesoso". Ever check out Rodelius's "Durch Die Wuste" album? Probably the closest to "Sowiesoso" I've found:
