Heart On sees the Eagles of Death Metal’s formula finally perfected, a collection of infectious, flirtatiously simple tracks with no substantial underpinning apart from shared celebration of hedonistic escapism. Lead singer Jesse Hughes muses on tight pants, hot girls and fast cars, reveling in one-liners and catchy come-ons.

Concise choruses and tight, compact riffs form the core of each track, laid over a minimal beat and swirling around occasional bursts of percussion, keyboard and the oddly competing guitar solo. Tracks miss variation, the same selection of chords repetitively underlying dissonant vocals. But never mind — their brief duration prevents the induction of monotonous oblivion.

“Wannabe in L.A.” epitomizes the group’s shtick, a short tribal intro giving way to a perfectly balanced ode to retro rock that ends before it exhausts its novel simplicity. The swagger screams of Queens of the Stone Age and White Stripes — though not quite on par in lyrical weight, as Hughes croons the follies of his own debauchery. But hey, what about that band name?

The Eagles of Death Metal will perform live in L.A. on Nov. 3 for “Jimmy Kimmel Live!.”
