Jazz with less horns??

If your roots are in 70's & 80's rock, you might enjoy Fourplay. I'd also suggest Fattburger, Norman Brown, George Duke (after hours), Keiko Matsui, Peter Horvath, and I like the softer horn sound of Chris Botti ...just a few I like. Sade is fantastic. However, Diana Krall is my favorite! I'm a bit biased right now because I just saw her in concert last night at the Oakdale theatre in CT. There's little on her CD's that bring out the magic of her live performance! She can sing and play piano at an emotional level that the recordings can't reproduce ...on ANY home system! It's humbling ( frustrating ) to get that glimpse of what we audiophiles aspire to recreate. If you get the chance, a must see! Great back-ups too!

if you like solo piano, trios and quartets which are on the mellow side, try bill evans stuff. he is one of jazz's greats from the 60's.

I'll second everybody on Mr. Campbell's list and add three other piano trios:
1) the early Nat King Cole Trio (which is available in a number of compilations, I believe);
2) "Money Jungle": Duke Ellington, Charles Mingus, and Max Roach--definitely on my shortlist for greatest piano trio recording ever;
3) Jacky Terrasson's first 2 albums (the eponymous one, and "Reach").

that all depends what type of jazz you like listening to, but I would definetly try Bud Powell, Monk, Bill Evans and Oscar Peterson.
