Heavy Jams

Insane Kraftwerk radio performance from Bremen 1971. The band featured the merry men from Neu! at that particular event so yes, indeed, you need to investigate this.
Hat Tip: Brian Turner/WFMU

On a more contemporary level, a truly great live show from Finland’s finest, Circle (well, never forget the mighty Hurriganes, of course, or, er, The Rutto, for that matter), from their triumphant 2006 US tour.
Hat Tip: No Quarter
