Flash Delirium is the track you’re most likely to have heard from Congratulations.
It was given away as a free download against the ideals of MGMT, who told NME.com they really thought the album should be heard as a whole.
And maybe they were right. Heard alone, Flash Delirium was and still is unexpectedly weird, scatterbrained and indecisive.
It features vocals from Royal Trux’s Jennifer Herrema and tears through influences including the Sgt Pepper period Beatles, Love and T. Rex before it finally settles into its stride in a Phil Spector-esque Wall of Sound.
Flash Delirium was possibly the first track off the blocks because it’s a microcosm of the album. Alone, it’s frenetic and unpredictable. In context, it works.
