The Beatles - A Day In The Life (0.00)
Lynyrd Skynyrd - Free Bird (0.38)
Metallica - Hero Of The Day (3.72), One(3.47)
Ravel's Bolero has a "huge build" at least in some versions: http://labs.echonest.com/loud/?songId=SOKNXIQ13134384E1B
Metallica's To Live Is to Die actually has quite a quick build http://labs.echonest.com/loud/?artist=&title=to+live+is+...
Godspeed you! Black Emperor's works are more ebb and flow than sustained build throughout the track http://labs.echonest.com/loud/?songId=SOJBUTX1311AFDAC27
