Me neither. It's a pretty vague term actually, like rock or pop.Usually it's heavily loop driven jazz, in the veins of instrumental hip-hop, however it does extend to nu-funk, nu-jazz, fusion, jazz-funk, pop and even that jazzy chiptune stuff I do. A lot of acid-jazz can be pretty much electronic free jazz, which isn't so down my alley, too atonal for me.
Here's a conservative, loop driven type band you might dig.
Also, check out
, they're less of that loopy yawn hip-hop side and way more funk. So flippin' great please say you know them. Also they're British.
These guys are also pretty HAWT. Again, I wouldn't've called 'em acid-jazz, but hey.
Another band on the British scene.
