I will have to look back at that year (1979) as it had already led to the Buzzcocks who have been getting lots of play on my ipod lately (thanks Derek)...I seemed to have been spending the last half of the seventies getting into 60's music so i missed the sharp change from disco to punk and only caught on in the early eighties, (which meant I missed it completely as the heart of it was so brief)....thanks for some of those more obscure late 70's tips....
I did look at 71 but without a beatles album....I couldnt quite justify it....68 is great too (wherefore art thou list Brian)....I thought you would pick 67 though....
actually 1989-91 is a very similar transition.(granted that is 3 years not 1) ..from oldies like the cure(disintegration, ) Lou reed new york, morrisey (viva hate) and newcomers stone roses pearl jam 10 nirvanna (nevermind) pixies (doolittle) again it is the changing of the guard...what about 1999-2001??
