Calvin Harris' New 'Slow Acid' Video Is A Trip: Watch Now

'Summer,' this ain't.

Calvin Harris is kicking it old school with his new music video for "Slow Acid."

The latest track released off of Motion drops both the vocals and the radio-friendly pop sound of his recent hits, returning to EDM's more Prodigy-esque roots.

The clip also has a certain "Smack My Bitch Up" quality to it, as it follows a silver-painted woman on an all-night bender, complete with blazing guns and a convenience store robbery. Coupled with the pulse of the music, it's all pretty trippy.

"Slow Acid" takes a wide turn away from Harris' recent singles. The VMA-nominated "Summer" topped the charts with its feel-good beats and catchy melody, and the soulful "Blame" featuring John Newman was equally ready-made for radio.

As Harris recently revealed, Ellie Goulding, Gwen Stefani, Tinashe, Haim and Big Sean will all appear on his fourth studio album. Motion drops November 4.
