I've never actually watched a Mike solo riff. I've said this in another thread, but the single riffer style has never worked for me. I've always felt that it should be Mike and AT LEAST one other person. The one exception is The X-Files movie with Bill and Mary Jo Pehl. I just feel that the chemistry between Mike, Kevin and Bill creates the sense that, if you are watching it alone, you really AREN'T watching it alone. This isn't a criticism of single person riffs, in fact it's probably my own preconceived notions that keep me from checking them out. I really can't point the finger at anybody else other than me in this.
