Shapiro and Resnick are originally from New York and New Jersey, respectively, but began to perform for the first time in Boston in 2007. The two currently reside in New York City. Timeflies includes elements of hip-hop, pop, electro, R&B, and rap in their music.
Attending Tufts University, the pair met in fall 2007 at a college party where Shapiro freestyled over Resnick's beat boxing. Resnick later invited Shapiro to be the singer for The Ride, a funk band he was part of. The Ride dissolved after some members graduated but Resnick and Shapiro started recording together in the spring semester of their senior year. Eventually calling themselves Timeflies, the duo posted songs to an increasingly popular YouTube account in which Shapiro did vocals over beats Resnick produced. The group's exposure increased when Shapiro's housemate - now the general manager of Timeflies - Jared Glick sent their song "Fade" to various music blogs.
In late September 2011, Timeflies released their debut album, The Scotch Tape, which rose to #8 on the iTunes overall chart and #2 on the iTunes Pop chart within 24 hours of its release. Shapiro and Resnick were dubbed “musical masterminds” by Vanity Fair. That same year, they began to perform college campuses and music festivals across the United States.
On August 14, 2012, Timeflies released their official application to the Apple App Store produced by the development team of Matthew Hamilton and Graham Tomlinson.
On November 27, 2012, they released their first EP, One Night. Within 24 hours of its release, One Night reached #2 on the overall iTunes chart and was #1 on the iTunes Pop chart. The EP debuted on the Billboard 200 at #29. The title track from the EP climbed to #84 on the iTunes Pop charts and "Swoon" debuted and peaked on the Billboard Rap Digital Songs at #45. Billboard named them one of their 13 artists to watch for in 2013.
On February 22, 2013, they announced that they had created their own label, Forty8Fifty. The label is partnered with Island Def Jam Music Group. Their next full-length album will be out later in 2013 and will be released on the label.
Their debut single, "I Choose U", was released on April 1, 2013 to digital retailers and was released to American radio under Island Def Jam Music Group. The single was remixed by Fedde Le Grand and on June 3 released on his official Soundcloud page. The song received as many listens in three days as Le Grand's most recent single Rockin' N' Rollin' acquired in one month.
