The three sisters, born and bred in Los Angeles, who lead this surname-monickered band are all in their twenties, so the depth of the classic-rock influences on display on their debut LP seems curious — until you learn that they've been touring and recording literally since childhood. The trio spent years playing with their parents in a band called Rockinhaim — hence the flashes of Joni and Fleetwood Mac — and there's also a strong R&B streak, ranging from the 1970s to the '90s (guitarist/singer Danielle Haim toured Cee-Lo, as well as Julian Casablancas). But what really makes Haim special is the way these influences are fused organically and un-self-consciously into their diverse and deceptively complex pop songwriting, which was evident on their debut single "Forever," released back in early 2012. It's like someone genetically engineered a group to combine those influences, and out came this lovely hybrid. Props to producer Ariel Reichstadt (who's on a roll this year with Days Are Gone, Vampire Weekend, Charli XCX, Sky Ferreira, and lots more) for helping to make such a melting pot sound so effortless.
