When John McLaughlin fired the other 4 members of Mahavishnu Orchestra in 1974, they picked up and moved on. They had already been doing their own songs live in the last few months of the MO, and these tunes later found their way onto the early solo albums.
Perhaps one of the best efforts was "Like Children", by Mahavishnu fiddler Jerry Goodman, previously with The Flock, and keyboardist Jan Hammer. On this album, the two of them played every single instrument. Jerry turned out to be a very good guitarist, and Jan turned out to be a not too shabby drummer.
Finally available on CD...
