Funky/fusion jazz with heavy base emphasis....

Medeski Martin & Wood - any titles (very groove oriented)

Johansson Johansson and Holdsworth - Heavy Machinery (no bass but has HEAVY synth bass grooves)

Gong: Expresso II

Wayne Peet's Doppler Funk: Blasto! (nine winds label)

Hebie Hancock: Thrust

Kazumi Watanabi: the one with Bruford and Jeff Berlin...think its called "spice of life"

John Fumo: After the Fact (has fair amount of horns but it still grooves)

Doctor Nerve: Armed Observation/Out to Bomb Fresh Kings (2 on 1 cd)

Praxis: Transmutation

Dedalus: Dedalus (vynyl magic label)

Miles Davis: Decoy

Grade Boy All Stars are prettty groovy, but do have some horns.

Billy Cobham: Spectrum, has some funky tunes

Zao: Shekina, actually a prog lp but some of the funkier tunes blow me away, beautiful record

Oops! Sorry, there is no Grade Boy All Stars...they are called Greyboy Allstars. I only knew them from a radio program and it sounded like the announcer was saying "Grade Boy All Stars"! Went to a record store and DISCovered the truth

BTW, I think Maraketz recomendation of Material "Hallucination Engine" is good one, it's more bass heavy & groovy than Praxis (also Bill Laswell produced). Get Material and forget about Praxis, I dont think it's what you are looking for (based on your description).

Marakanetz, sorry I spelled your name wrong if you notice above...BTW if you are still following this post could you recommend some Pekka Pohjola records? I only have "Consequences of Indecisions" w/Oldfield and Moerlin (great lp).
