"After years of resistance, Joni opens the vaults: If Mitchell was ever concerned she might give too much away, dilute or dissolve, this collection of radio and TV performances, live sets and home recordings - including 29 previously unreleased tracks - does the opposite, enhancing the listener's wonder at her rapid evolution, shoreline to treetops in under four years. Organised chronologically (partly under advice from Neil Young), the collection stops before her 1968 debut, 'Song To A Seagull'. That she had so many songs - not least "Both Sides", "Now", "Urge for Going", "The Circle Game", even "Conversation" and "Little Green" (...) - that didn't make it onto her first album suggests not only ceative overspill, but also a remarkable clarity and confidence".
