I wondered if there was any site with where i could download backing tracks?

Not necessarily from a famous song, just a chord progression with drums that I could do improvisations over.
Thanks . Tried google, and didn't get any results.

Do you have any experience with this site?
I've used it a few times, but only for famous songs, which doesn't sound like what you're looking for. I know they have some blues backing tracks on there though. I'll go look around.
Okay . I think the site looks very good actually.

I just can't seem to find those blues thingies you talk about.
Ok, when you click downloads at the top scroll down the list to "jam tracks". Click what you want and at the bottom of the donation page there's a thing you can click to get the song.
