Boston Volume 1 icollects live recordings from an earlier era of Fleetwood Mac's colorful history. The set features the classic blues line-up of Mick Fleetwood, Peter Green, Danny Kirwan, John McVie and Jeremy Spencer. Originally recorded at the Boston Tea Party venue over three nights in February 1970, for a planned release later the same year, these recordings were left in the can, unissued, following leader Peter Green's sudden decision to leave the band a few weeks after the dates. Tracks from the shows were eventually released in various forms in the mid '80s but these releases were blighted by poor sound sources.
