Backing Tracks

I'm looking for free backing tracks to play along with, so that i can improve my improvisation technique. I'd prefer tracks that are not others songs, more of a "jam" track. Do you guys have any suggestions on where to go?
I'd greatly appreciate it

i personally like this site
http://www.jamcenter.com/

Thank you so very much :]

The quility is good and you can preview or download and import to your fav software.

Make ur own in Guitar Pro:p..i doxD

True Dat G!!!

on the other hand sometimes you just want to practice some technique and don't want to have to spend all the time creating drum, bass and other guitar parts.

yeah thats what i do now.

You always have the option of the jam machine on this site, though its only chords and doesnt give you a drum beat
