Philadelphia hip hop band Chiddy Bang sampled the Knocks' "Blackout" for their single "Here We Go" (featuring Q-Tip) from their EP The Preview.

[3] In June, the duo took the number one spot on the website HypeMachine with the track "Learn to Fly", which reached 100,000 plays on SoundCloud within a week of its release.

Afterwards, the duo released another successful single, featuring St. Lucia, entitled "Modern Hearts", in the beginning of 2013 and earned the group another number-one placing on HypeMachine and reached the 100,000 plays mark on SoundCloud in four days.

[8] Throughout the rest of the year, the duo began working on their debut album, entitled 55, which featured collaborations from the likes of Fetty Wap, Cam'ron, Wyclef Jean, Carly Rae Jepsen, Matthew Koma, Magic Man, Alex Newell, POWERS, Phoebe Ryan, Justin Tranter, Walk the Moon, and X Ambassadors.

Once released, there was a post-success for the duo, as songs from the album were promoted on advertisements and shows across the US, as well as producing musical material for other artists for the first time, including Carly Rae Jepsen and Wyclef Jean.
