Requesting jazz quartet CD suggestions

You guys have given me quite a few leads. Perhaps most beneficial is the info on kplu.org music stream (thanks Celtic66!). I just hook up to them, put on the headphones while surfing and take notes on the various artists. The jazz they play is exactly what I'm looking for. I have found several CDs that look interesting such as: Ray Brown Trio, Scott Hamilton Quartet, Holly Cole Trio and others. Many thanks once again, to all, for the direction you guys provide!

Jeez, this is easy. John Coltrane, Miles Davis (add a horn or two now and then), Sonny Rollins, Joe Henderson, Chick Corea, James Carter, Josh Redman, etc., etc. These are just some classics and any trip through the jazz section of a good record store (Virgin for example) will tip you off to more.

Look for these labels:

JVC XRCD - Blue Note - Impluse - Y2K 20 bit (lots of different labels' reissues on this line; they are always in jewel box inside cardboard sleeve) - and others I can't quite think of right now.

Just an update for you guys who contributed here. I found many artists on kplu.org through the suggestion of Celtic66. I'm still scoping out the others you guys recommended. I p/u the following:

Ray Brown Trio - Live at Starbucks
Dave Brubeck Quartet - Time Out
Ruby Braff George Barnes Quartet - Live at the New School
Mark Whitfield - True Blue

Thanks to all!

Cannonball Addery quartet live in San Francisco - Hybrid SACD. It is a stunning disc.
