Adagietto from Symphony No. 5 by Mahler
After the first three movements of this monster have thrown you around, made you cry or run for cover and then left you for dead, Mahler graciously inserts this "little Adagio" as sort of palatte-cleansing respite... but don't think you've reached dry land. The tempest takes on a different form - deeper, sadder and bigger than all the previous cacophony put together.
