I am older, somewhat annoying dude around here, But I have a more open mind than it might appear.
So name some really hot, hard driving cuts, post, 1999!! Bands whose genesis was after 1999.
Now I am not talking technique unto itself, I am talking about an intense groove machine.
Here are some artists/ bands, that comes to mind from the mid to late 20th century.
James B
Average White Band
Stuff with Richard Tee
most band Steve Gadd graced
Earth W fire
Eddie palmeri
Tower O P
Tommy Sims
Michael McDonald
Marcus Miller
Herbie's Hancock's Headhunter band
Chick Corea's Return to Forever
early Motown hits- though as time went forward, the groove weakened
Jaco
Elvin Jones
Tony Williams
So many cuts, but here are a few good ones
Bonnie Raitt's "Something To Talk About"
Aretha "Respect"
Annie Lennox "Would I Lie to You"
Steely Dan "Aja"
These are the latter part of 20th Century.
Those who wish to refute my bias towards the past, please do so, I really want to hear new and intense grooves.
