D.D.: that's the Enja Horst Weber label, the Winckelmann has been active all the time and bringing us some goodies regularly. Weber has not been really out of business, it seems - he did, for instance that duo disc (don't have it) of Shepp and Waldron, two years ago or maybe three.
I'm not really interested in the Takase - she did an earlier programme, I think exactly the same band, but with Fred Frith on guitar, and no trumpet playing W.C. Handy - don't know the disc, but her Willisau gig was... well, annoying. You didn't really get to know if they actually WERE playing that bad and amateur-like, or if they consciously TRIED TO APPEAR as amateurs... Mahall was in charge of spoken introductions, they were NOT funny yet some of them went longer than the music to follow (4 minutes of talking, then 3 minutes of music - glad that rationale applies not to all concerts and neither to CDs...)
end of rant.
That disc you have with Dorge sounds pretty cool! Didn't check out Khan Jamal, but it seems he's one of more (or most) interesting vibists coming on us since the sixties.
