Uptite is NYC (the yellow label that had Tail-Feathers on) (The "Superlatives" Uptite label was Philly as far as I remember...)
Unart is not the same label, its a subsidary (am not too sure about that but you're probably right)
Tac-Ful I believe to be NYC thru the Roosevelt Grier connection (hew as from NYC, wasn`t he ?) (Tac-Ful is Hollywood, Cal. At least that what it says on the label)
Jet Set was NYC...maybe people get confused because of the Eddie Singelten/Washington connection...? (Andy Rix' article on Shrine mentions that E. Singleton leased some tracks to Jet Set, that being another local DC label, doesn't it?)
