Hi Midge,
I have spent some time at the British Library going through copies of the music press from the '70s, mostly the Melody Maker (because they are available) and some (late '70s) NMEs. It seemed to be routine for some journalists (mostly NME) to slag off most acts/albums/concerts, presumably in a vainglorious attempt to make a name for themselves off the back of yet another bitter review of yet another well-known performer. It got pretty monotonous/predictable after a while... I remember a two-page interview with some herbert from the US (I can't remember his name) who, in 1975, confidently assured readers that David Bowie was washed up/finished/a spent force. Such benighted soothsayers seemed to be around for some time back then. For the most part the Melody Maker adored Mr. H. by the way.
