Mott vs. Eagles... I'd have to go with Mott, but in truth I have a best of for them and only the first eponymous LP for Eagles. Hate is too strong a word, more like almost complete indifference, or like Seven Of Nine might say "Glenn Frey is irrelevant"? Now Gene Clark I can get worked up about, his music grows and grows on me over the years until it's become indispensable up to his demos and last sessions, very rare. So it's not a country-rock bias. The Eagles' cut of Train Leaves Here This Morning is a limp noodle next to the Dillard And Clark Expedition original.
The 70s... I think the 60s sides of Bowie and Marc Bolan already said it well before the 70s arrived. Tell me why Bolan's Third Degree single on Decca isn't equal to everything else he ever recorded combined? I'll back Slade over most of the other big names with maybe one double A side for Sweet (making them the 70s equivalent of Freddie & the Dreamers). By the 70s people knew what they were doing, i.e. a formula (Kiss army?), spread out over an entire decade. Excitement mostly feigned, new kids assumed it was expected of them from watching older siblings? Thank God for The Ramones, Devo and Television, Gang Of Four, Joy Division or Buzzcocks, and other more local scene know nothings doing it 'all wrong' in the late 70s. We were all soooooooo sick of the bloody Eagles and other cocaine fueled mega formula industry product (even if I did wear a Styx Grand Illusion shirt).
