Riff of the Week

I came across a great resource for all you guitarists out there. It's called Riff of the Week. It is a weekly vidcast by a guy named Dave Weiner. Dave is the 'other' guitarist for Steve Vai's band. Dave takes a few minutes each week to show a cool riff, technique or tonal idea. He also has put up a section on his website with a bunch of background tracks for practicing improvisation. They range in style from Jazz to Metal, in several different keys and modal tonalities. Like I said, a great resource. So, check it out at http://www.riffoftheweek.com
