Usually, I am glad to awaken, and I like the pre-dawn darkness. I would also second Alec Guinness's Haydn suggestion. The sonatas especially are consistent demonstrations of sanity. And God knows, Patrcik is sure right about Stockhausen:
I’ll take Haydn under advisement. A saner choice, certainly, than Karlheinz Stockhausen, whose passing in December belatedly brightened an otherwise drab year. The composer will be remembered for describing the Sept. 11 terrorist attacks as “the biggest work of art there has ever been.” Not surprisingly, he died of heart failure.
