If the Greek letter “∆” evokes memories of a 10th grade math test or your alma mater’s blondest chapter, it’s time to readjust your brain dials. The British alt-pop band ∆ (pronounced Alt-J and referring to the command used on a Mac keyboard to achieve the Greek letter “Delta”) has been making music since its members met at Leeds University in 2007, but the release of their debut album An Awesome Wave has taken the group from GarageBand to rock stars at a startling speed.

Their video for “Fitzpleasure” is as intense and eccentric as the band’s stylistic influences. Set in an otherworldly gothic church, two white-sheathed creatures interpretive dance their way through the intricate web of trip-hop basslines, indie quirk, heavy synth, and atmospheric bhangra that ∆ has melded and established as their trademark sound.

An Awesome Wave is out now on Infectious, and will come stateside via Canvasback on September 18th. Until then, check out the Jim James remix of “Fitzpleasure” that we posted on yesterday.
