I stumbled upon a really interesting article last night on the history of Mahavishnu Orchestra, one of the greatest jazz-fusion bands of all time. The article points out some of the influences they had on other groups, and reveals some interesting history I didn't know (like lead guitarist John McLaughlin being asked to join Weather Report, a band that would go on to make some terrific jazz-fusion of their own). It's definitely worth a read if you're familiar with the group, or even if you aren't!
