I just ordered a bass/tenor duo disk of Lafitte w/ Pierre Boussaguet, titled Crossings. It was only 3EUR so hard to go wrong. If I understand correctly this was recorded (released?) in 1999; you write he died in '98?
Good to know that those Black & Blues are also worth the price. Will seek these out if I stumble on them; they do seem to be available. I see he's also on a disk with Saxomania (1993, IDA), anyone know what to expect of that? It seems this is a group of 5 saxes + rhythm... looks interesting.
Lafitte has a really lovely velvet tone; much like Byas I'd say. Besides the Blue & Sentimental disk you mention, I also have the JiParis disk of Jack Diéval and his group, which is very nice swing to bop in a pseudo radio broadcast setting. That Hampton (AmSwiParis) you mention is also part of my modest collection; he's also featured on 4 tracks of the Lucky T disk from the same series. Stunning material.
Found this about the Rivièra Festival:
bof!
