My personal favorite is the Gozo Shioda Sensei anthology tape. Timeline is 1962-1990. The tape can be ordered online at
http://www.queststation.com/quest-e/aikido.html. You want tape SPA-8019 KAMIWAZA GOZO SHIODA, ALL REOCRDS 1962`1990(Japanese) 40min.$83
There's no holding back on this tape. Shioda Sensei at his best.
Cheers ...
