So you're lost at sea...you wash up on shore after bobbing in the Atlantic clinging to a 2 x 4 piece of driftwood for 4 days. You crawl onto an uncharted desert isle (sorry Gilligan). You know you're here for a long,long,time. The sun burns the seawater in your eyes. You look up as you collapse onto the burning sand and you see a blurred figure of a musician(s) standing before you. "My god" you cry out with your last bit of strength, "I can't believe my good fortune. If i'm to be stuck here for years, at least I can listen to you play 7 days a week"...So who would it be? Dylan? Charles? Stevie Ray? Chopin? Cohen? The key here is who would you not get completely bored with after a week or so and then have this artist or group turn your experience into a "groundhog day hell" for many years after. Can you think of someone who's songwriting repetoire and skills would have the depth and talent to stand the test of time...your time?
