Dating this one is a bit tricky – recorded in 1971, released on CD unofficially in 2005 and officially in 2007, but on vinyl for the first time in 2020.
Massey Hall on Victoria Street in Toronto was home to the Toronto Symphony Orchestra and seats under 3000. This release is the Volume 3 in the Neil Young Archives Performance Series (though the numbering is a bit idiosyncratic as there’s a Volume 2.5 and a Volume 00).
It’s just Neil solo – no other supporting musicians or vocalists other than the audience singing along. It’s a great show and a great release, well edited/restored, packaged, etc.
I picked up my copy at Mystic Disc, in Mystic CT
