Rimbaud has some wonderful poetry that will give some great imagery to go off of.

Utilize Salvador Dali and Max Ernst's painting and think of what kind of melody or sound would go along with some of their works.

If you're looking for something evocative and erotic, look into Marquis De Sade and his stories, as well as Decadent fiction from the 19th century.

I could go on and on but that's what first popped into my head to give you something to chew on for awhile :)
