Los Angeles-based Mariachi El Bronx started out as a punk band called The Bronx, but that was before its members discovered a collective love for Mexican folk music. The group fell hard for mariachi, and when faced with playing an acoustic punk rock set for a TV show, they decided to fully embrace that new direction and start a Mexican-flavored side project.

Bear in Heaven, the brainchild of Jon Philpot, spent the winter trimming down (from a quartet to a trio) and stocking up, releasing its third album I Love You, It's Cool this spring. To promote the record, Philpot posted it in its entirety on the band's website, but not before slowing the audio down 400,000 times. At its original tempo, Bear in Heaven's music is at once ambient and energized, resonating in synth-driven waves that swell and pulse through an electric sea.

Originally from Memphis but a resident of New York City for the past decade or so, singer-songwriter Megan Reilly has a fan in Sonic Youth's Steve Shelley, who helped her get her original record deal. Ever since, Reilly's country-inflected soft rock has evolved further into pop territory since her 2002 debut Arc of Tessa and 2006's Let Your Ghost Go.

Sharon Van Etten's raspy, elegant vocals and deeply confessional folk-rock have made her a rising star. Ever since her official debut in 2009, the heart-breakingly intimate Because I Was In Love, Van Etten has been expanding her sound and adding grit to her delivery.
