Tough subject, I can't even commit to a single artist I think.

I think the thing that makes those artists favourites is the quality of their body of work anyone can capture a moment once but years worth of moments? For groups my current leaning is to the Clash, but can't decide on Spanish Bombs or Clampdown. Solos provoked a good discussion last weekend with a friend, he taking Bowie and me Gabriel. Both spanning decades with consistant quality and influence. Current Gabriel fav is More Than This off his last one but Mercy Street still gives me shivers every time.
