(written on a train, in a hurry, into my phone - for some promotional purpose or other, I forgot - in other words, not a definitive list - but on the other hand, as a ultra-condensed core canon, not a bad place to start either)
T. Rex - Get It On, 1971
The ultimate Bolan boogie, slinky and so sexy - the blues shuffle made ethereal and elfin.
Alice Cooper - Elected, 1972
Hilarious political satire as Cooper pretends to run for President but sounds genuinely grandiose and megalomaniacal - while the music is punk rock four years ahead of schedule.
Roxy Music - Beauty Queen, 1972
Shimmering ethereal ballad from the most arty and experimental of the glam groups, featuring Bryan Ferry's lyrical evocation of a female glamour ideal who makes his "starry eyes shiver".
The Sweet - Teenage Rampage, 1974
Hysterical fantasy of youth taking over the government and rewriting the laws, propelled by tough riff action that anticipates the Sex Pistols.
David Bowie - Fame , 1975
Blistering, scorching funk meets Bowie's frigid hollow-souled anguish at the paranoia and disorientation of stardom.
