Mahavishnu Orchestra is tough to replicate. One cd that I have enjoyed in the same vein is a T Lavitz production called "School of the Arts". T Lavitz was the keyboard player for the Dixie Dregs. He did session work for Santana, Widespread Panic, and others. His solo efforts are upbeat jazz fusion and his band Jazz is Dead did some interesting Grateful Dead covers. School of the Arts features violinist Jerry Goodman from Mahavishnu and is great. You can get a used copy on amazon.
