Hal Leonard Bass Play-Along Series - any good?

[clodhopper]

I'm looking for some backing tracks to play along to. I've got Aebersold stuff, Band in a Box, and various drum loops but spotted these:
Bass Play-Along - Hal Leonard Online
Any comments or reviews on these?
Or any other options for rock/funk/blues/RnB play-alongs for bass, ideally where the bass can be silenced.

they're great ...also ....musician's institute press has a great one - Grooves for Electric Bass!


you couldn't go wrong with the Funk, RnB, Blues Rock, Police play a alongs ...or whatever you're into ...those would be my picks...
