1977... Hawkwind, Purple, Steeleye Span; with The Stranglers and Buzzcocks and VdGG/Peter Hammill looming (I bought Live Vital because the cover was interesting, and that was that...), and then the post-punk contingent. Hawkwind stopped being interesting about 1980, IMO, though I still listen to the first few albums (but I always hated Silver Machine). Not listened to Deep Purple since about that time.
