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 issued in various forms in the mid-80s but these releases were blighted by poor sound sources. The discovery of the original 8-track tapes and a number of previously unreleased tracks in the late-90s allowed the material to be re-mixed, re-mastered, and substantially overhauled for release, and Boston Volume 2 follows on from the previous Madfish/Snapper offering - Boston Volume 1 - which was released in 2013. Ushering in Boston Volume 2 is the floating "World in Harmony," the only Peter Green/Danny Kirwin co-written track in the Fleetwood Mac catalog, and one that, has never appeared on a studio album.
