Hawkwind first came together in 1969 formed in Ladbroke Grove London. The band very soon gained attention or notoriety for their willingness to perform concerts for free at numerous events in and around the Ladbroke Grove area. They were soon signed to a recording deal releasing their self titled debut album in late 1969 and have regularly recorded and released albums ever since. The band also scored a massive hit single in 1972 with the perennial rock track Silver machine and a massively successful album Space Ritual in 1973. Although going through a number of line up changes over the last forty years the band have managed not only to keep the title of "People's Band" but are still led by founder and guitarist Dave Brock and continue to play concerts and release regular studio albums.

In keeping with the bands forward looking attitude on official bootlegs the latest release comes from the bands vaults and comes from 1989 when the band were celebrating their twentieth anniversary. This album was recorded in Minneapolis on the 4^th of October 1989 when the line up of the band at this time featured Dave Brock, Harvey Bainbridge, Richard Chadwick and Alan Davey. Songs featured in the set captured on this double CD include Magnu, Hassan I Sahba, Wind of Change, Brainbox, Damnation Alley and Ejection.
