I think I would actually cheat and take an MP3 player with several megabytes of storage... However, trying to keep it down to eight pieces of music, these would be near the top of my list:
"Gimme Shelter" by The Rolling Stones.
"Maybe I'm Amazed" (live) by Paul MacCartney.
"Bless These Children" by Bill Boazman (aka Sonny Black)
"Nimrod" by Elgar (Sir Colin Davis and the LSO)
"The Dance of The Comedians" by Smetana (Conducted by Robert Casteels)
"Across The Hills" by Paul Downes and Phil Beer (brilliant version of a Leon Rosselson song)
"Come On In My Kitchen" by Robert Johnson
"Empty Handed" by George Papavgeris.
The first book I would want to take would be the Complete Works of Shakespeare, because it is the one which best stands up to re-reading. I find something new in the plays every time I read them. If that was taken as a given, I might toss up between W.Somerset-Maugham's "The Razor's Edge" or the more recent novel,"Captain Corelli's Mandolin". The luxury object would have to be my gorgeous Fylde Oberon guitar!
