I think the type of fusion band typified by Mahavishnu Orchestra, Weather Report, Return to Forever, Passport, Caldera, Isotope, Al DiMeola, Billy Cobham, and other 70s fusion band is that this type of jazz was supplanted by more accessible (read: melodic) smooth jazz by the likes of The Yellowjackets, Andy Narell, Bob James, Michael Franks, George Benson, Bela Fleck, and Spyrogyra. I like both genres but they are definitely different. Some great 70s jazz is also found on the CTI labels but tends to be more pop-oriented.
