No prog band can escape Rush's influence. Dream Theater's thunderous “Pull Me Under” reflects the trio's heroic dynamics and skyscraping vocals, and Porcupine Tree's spacey ballad “Black Dahlia” speaks to 21st-century prog rock's love of the Canadians' gauzy synths. Their legacy also reaches alt-rock: Foo Fighters' “Headwires” boasts busy fills and snaking melodies similar to those heard on Rush's records from the ‘80s.
