When you look at my top 3 I think it's quite easy to spot that I am a product of the 80s. My top 3 are:
John McGeoch (Siouxsie and the Banshees, Magazine, PIL, etc) - amazing unorthodox talent and much missed (probably the guitar equivalent of Mick Karn).
Geordie Walker (Killing Joke) - again, an amazing unorthodox talent.
Andy Taylor (Duran Duran, Power Station, etc) - at first consideration, kind of the opposite of my other two choices but still a little unorthodox in his own way if you consider his hard rock playing style in the context of an 80s pop band.
