Neil Young Live at Massey Hall 1971

I recently bought Neil Young's archive release of "Live at Massey Hall 1971" from Toronto and it's incredible to hear the piercingly crisp vocals on classic songs like "Ohio", "Old Man", and "Down By the River". It's haunting and the intro's to some of Neil's mindset at the time (only 8 of the 18 played were recorded at the time).
