70's or the 80's... The start of the 1970's seen the end of the Beatles and the last gasps of the Woodstock hippy days.
In came Metal in its first forms, with Sabbath, Led Zep and Deep P.
King Crimson rose from Hyde Park and led the way with Prog Rock, Floyd, Genesis, Yes, ELP etc.
Along with it came the Glam stuff, Sweet, Wizard, Slade, don't forget Roxy I hear Stabba cry.... But what about E.L.O.!!!!!!!!
Oh yer, the Stones and the Who were at their peak right about now too... Not to mention Elton, Rod and Bolan
Go across the pond, giants like ZZ Top, Springsteen, Kiss,
