Krewella

Jahan Yousaf, Yasmine Yousaf, and Kris Trindl (aka Rain Man) formed the EDM trio Krewella in Chicago, Illinois. They got together in 2007 but didn't release their first material until 2011, when they uploaded a handful of songs — including the jagged, celebratory "Life of the Party" — to their Soundcloud page. In 2012, they self-released their first two EPs: Play Hard (June), featuring the reggae-flavored "Killin It," and Play Harder (December). The former reached number ten on Billboard's Top Dance/Electronic Albums chart. The same year, the trio became a staple of the festival circuit, including New York's Electric Zoo and Texas' Meltdown.
