Original Jefferson Starship bandmembers Marty Balin, Jack Casady, and Paul Kantner were back with some songs about the millennium, protests, and life in general on 1999's Windows of Heaven. Guest vocalist Grace Slick, who sings on one track, makes the album almost a full-scale reunion. New bandmates Prairie Prince (the Tubes) and T. Lavitz (Dixie Dregs, Jazz Is Dead) add even more spice to the mix, as the offshoot of one of San Francisco's finest '60s psychedelic bands prepared itself for the 21st century. Vocalist Diana Mangano sounds remarkably similar to her predecessor, and helps to create a very Jefferson Airplane-ish vibe. This may not be the best album from the Starship/Airplane catalog, but it served as a stunning reminder that, as of 1999, much of the '60s psychedelic subculture was still alive and well and standing at the Windows of Heaven.
