The Oklahoma band has nothing left to prove — no lofty commercial standard to maintain, no gigantic hit of the variety anyone expects it to re-create, and no core sound whose boundaries and limitations must be pressed against with great care.

Wayne Coyne and his co-conspirators have long been liberated and encouraged to indulge their whims, especially on their 13 studio records.
