Good question.
Music I was listening to in my teens and early '20's, like most people I suppose. What seeps into your brain in your formative years stays there forever I think.. So..
'
Classical Gas' - I'd never heard a guitar played like that before.
John Martyn's delayed guitar patterns, a whole band from just one guy.
Stuart Adamson from The Skids and Big Country and the wonderful memorable hooks he provided for very song he played on.
Mike Oldfield - the idea that such a young man could conceive a piece like Tubular Bells was a revelation to me, and made me want to record.
Martin Barre from Jethro Tull - every guitar part was there for a purpose - wonderful use of counterpoint and harmony to the vocal melody.
Andy Summers - getting a haircut when I was 19 and hearing those huge chorused chords on the radio in 'Walking on The Moon'. Wow.
Dave Hill from Slade - every song they brought out was a hit in the UK in the early '70's, and every one was chock full of brilliant riffs.
Dave Gregory and Andy Partridge from XTC - such a brilliant interplay between two very different players - really inspiring.
Wilko Johnson from Dr Feelgood -simplicity and energy - no bullsh!t.
David Gilmour - as far as I could see, the only guitarist in a prog rock band playing in a blues style, with economy and emphasis on feel, rather than flash licks.
