Some hints? A tittle difficult, as they easily come close to identifying the tunes or musicians. But let me try:
# 1 is from a Riverside LP that many here like very much - the tune was identified. I'm puzzled as I thought this version was a giveaway track.
# 2 & 10 feature the same pianist.
# 3 The trumpet, as I said, is not his main instrument, it isn't even a horn. It is a Prestige album this is taken from.
# 4 This brass band also worked with Carla Bley and decided to do some more as a unit.
# 5 & 8 & 12 are an All Stars band with varying personnel that recorded a string of albums for a British label between 1995 and 1999, it was named after a part of the label's name, which doesn't suggest jazz albums.
# 5 & 12 feature the same tenor player
# 6 is co-led by a very famous bass player with a strong affinity to Brazilian music
# 7 the singer is from Venezuela and was included on one of my previous BFTs.
# 9 was identified
# 11 is impossible to guess unless you have the CD
# 13 was released on a compilation on the same label that released the All Stars recordings of # 5 & 8 & 12 and is from one of the sessions of these All Stars.
# 14 is connected to # 4 via its co-leader. I included a track of this band on one of my previous BFTs.
So will this help? Anyway, I will post the reveal on Tuesday.
