I'm waiting for a bunch to arrive via various amazon.fr marketplace sellers - those were the best prizes (w/shipping) for me.
I can highly recommend the Thad Jones/Mel Lewis, Mulligan CJB, and Louis Hayes/Woody Shaw for starters.
The Don Redman may be a bit weak (albeit the great line-up it has), but I don't think there's a real clinker in the series (But I'm still waiting for the two Peterson/Fitzgerald/JATP and the two Hamptons, as well as the Coleman Hawkins... and I still have a couple of gaps).
Thanks flurin - I'll keep an eye open for the Jones/Lewis (can't believe I haven't already seen/got that one) and the Shaw/Hayes, for sure. The Quincy Jones is a keeper !
