The group emerged from the ashes of '60s legends Jefferson Airplane and in the '70s produced slick synth rock.
That was the point at which leader and co-founder Paul Kantner realised that his vision no longer existed and left.
Kantner reformed Jefferson Starship in the '90s - without Grace Slick - and they continue to perform to this day.
But this latest release is for collectors only. Recorded at the Roswell UFO festival, it contains rehearsals and the main show and if you were there it's okay as a souvenir. If you weren't - avoid.
The versions of classics Somebody To Love and White Rabbit are just bad karaoke and the sound quality is appalling.
If you want to hear the band at their best invest in the Airplanes' '67 release Surrealistic Pillow on which Slick's haunting voice still can't be matched.
