Jazz with less horns??

Chick Corea, Bela Fleck and the Flecktones, Thelonius Monk, Herbie Hancock, Martin, Medeski and Wood

Jon Hassell plays synthesized trumpet and doesn't seem horn...y at all rather than fully electronic.
Andy Summers(Police) - The Last Dance of Mr X .
Brand-X is a fankomenal blend of famous musicians that you might like. Solos are maily performed by synthesized fretless bass by Percy Jones(a piece of virtuoso indeed)

Guitar and bass:
Marc Johnson
Kenny Burrell
Charlie Hunter
Bill Frisell

Piano:
Carla Bley with Steve Swallow on bass
Lynn Arriale
Eric Reed
Bill Evans (the piano player, not the horn player)

Art Pepper, sorry, he plays alto sax but may change your mind about no horns. My personal favorite.

In a nutshell, virtually any good jazz piano or guitar trio/quartet should get you started. Since you are relatively new to jazz, I'd suggest you try the following:

1. Piano groups led by: Bill Evans, Kenny Barron, Marian McPartland, Oscar Peterson, Art Tatum, Michel Petrucciani, Bill Charlap, McCoy Tyner, Tommy Flanagan, Teddy Wilson, George Shearing, Erroll Garner, Herbie Hancock, Chick Corea (check out his duet recordings with vibist Gary Burton) and Keith Jarrett (try both his recordings from solo concerts and with his "Standards" trio). If you have listened to enough jazz to enjoy some more challenging bop-style piano, then add Thelonious Monk, Bud Powell, and Horace Silver to the list. Last, if you like Afro-Cuban and Latin jazz, listen to the terrific work being done by Michel Camilo, Eliane Elias, and Chucho Valdes.

2. Guitar groups led by: Wes Montgomery, Charlie Byrd, Grant Green, Jim Hall, Joe Pass, Kenny Burrell, Bill Frisell, John Abercrombie, Pat Metheny, Tal Farlow, Herb Ellis, Barney Kessel, Jimmy Raney, Django Reinhardt, and Charlie Christian.

3. You can also try recordings by groups such as the Modern Jazz Quartet (which has no horns), or other horn-less groups such as the group that Ron Carter (bass player) led in the mid to late 1970's. His recording, "Piccolo" features Carter playing piccolo bass, plus piano, drums, and another bass player.

If you would like a more complete list, feel free to contact me directly and I'll give you some more detailed info.

If you like beautiful female vocals/jazz ballads (w/o horns-- except for Shirley;>), I'd recommend Jacintha, her XRCD2 "Autumn Leaves" is excellent. Also, Diana Krall of course-- all CDs are good, Shirley Horn "Ultimate", and Holly Cole "Temptations". Cheers. Craig

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!

mingus, liz story

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.

Accoustic Alchemy, Blake Aaron, Randy Bersen, Jay Azzolina, Tom Grant, Richard Smith, Tom Schuman, Peter White, Special EFX, David Beniot, Michel Camilo, Bob Baldwin, Michael Wolff, Alex Bugnon, Chris Ho, Freddie Ravel, Brain Nakagawa, Elaine Elias, Peter Escovedo, Earl Klug, Charles Fambrough, Larry Carlton, George Kahn, Gregg Karukas, Edison West, Ryo Kashiwa, Hiroko Kukubo, Steve Oliver, Michael O'Neill, Marc Antone, Jimmy Smith, Art Blakey, Steve Laury, Chuck Loeb, Ramsey Lewis, Metro, Chieli Minucci, Joe Fuentes, Dave and Don Gruisin, Ken Navarro, Ray Obiedo, Michel Petrucciani, Tito Puente, Joe Sample, Andy Narell, Dave Samuels, Louie Shelton, Roger Smith, Ricardo Silveira, Dave Weckl, George Winston and Rachel Z just to name a few more.

Thank all of you who took the time to make this awesome list I have started buying some new ones off the list so far so good thanks again
