While Jorma is a great musician, early on he leaned too far in the "every chord is a Dom7 chord" direction. Everything had to have a blues edge and some of the material suffers form this myopic approach. Certainly Airplane were an eclectic band, but at their best, they combined melody, harmony and cutting-edge sound techniques that worked more than they didn't. I dig stuff like Embryonic Journey and Water Song, but I'd personally rather listen to Jack with his hot, tubey overdrive backing Grace on piano on tracks like Sunrise, Crazy Miranda, and Silver Spoon. The non-Airplane albums by Slick and Kantner from '70-'73 are as good as anything by the Airplane.
