Not sure that is true. I’m certainly too young (59) to have seen them at the peak of their powers and I only really discovered them far later via people who had been influenced by them, as was the case with many bands (VU, MC5, Seeds, West Coast Pop Art Experimental Band, Silver Apples etc). When I found my first Can album, a lovely UA copy of Ege Bamyasi, it would have been maybe five or six years after I’d bought Metal Box new on release. I was slow on the uptake with Can as I was just too young for Eric’s in Liverpool, it had shut by the time I could regularly go to gigs. I mention that as apparently the DJ regularly dropped the whole of Aumgn, and I suspect had I heard it back then I’d have hunted a copy down pretty fast! I think I bought my copy in about 1985 or 86 (a record fair for £15, at the time the most I’d ever spent on a record).
