The key in this respect is viola player Mackenzie "No Relation" Roberts, whose energetic playing provides unexpected heft and welcome drama to "Jetpack." She also boosts "The Moon," which affords plenty of room for vocalists Brer Rabbit and Jonny 5 to stretch their syllables.
Granted, lines such as "I just wanna say welcome to the part of the show/Where the bass drum hits hard and slow" (from "One Love") need a crowd to make them work. But other parts of Platypus sound as strong on the car stereo as they do from the stage.
