funny enough i had Back Street Symphony on in the car last week! :)  some great stuff on there.
right now, i have Slash's album.  it's... tamer than i expected  :?  a few listens will give a better view of it, but first impressions are that the fiery guitar slinger of old has mellowed, perhaps a little too much.  so far, Fergie is actually the best singer i've heard!  
EDIT;  not the best singer i've EVER heard, just on this album :)
