In 2011, Karmin got a lot of attention when they posted cover songs on YouTube - watching their singer/rapper Amy Heidemann keep pace on Chris Brown's "Look At Me Now"
was captivating. Epic Records signed them that year and released their EP Hello
in 2012. Amy and her Karmin partner Nick Noonan met at the Berklee College of Music in Boston, and as demonstrated in their YouTube clips, could take on songwriting and production on their own. But under the eye of Epic, they were teamed with hitmaking producers and songwriters.
"Acapella" was the first single from Pulses
, their first full-length album, and their last with Epic - they left the label after it was released and went independent (they got married in 2016). Amy and Nick wrote "Acapella" with Sam Hollander
(Big Time Rush's "Big Night
," One Direction's "Rock Me
") and Boys Like Girls frontman Martin Johnson. The track was premiered on June 10, 2013 on Z100's Elvis Duran Show
and was released on iTunes June 25, 2013.
Talking about writing the song, Amy told Songfacts: "We came up with the melody first, like we always do. Melody is for some reason the easiest thing for me - it comes quickly and then I try to build a concept around it. Back then, I didn't value concepts the way I do now, so I'm pretty sure it was Sam who was like, "We need this to be a concept and then we can write these really distinct verses about the concept." And one of the gibberish vowels that I sang over the initial melody sounded like the word 'acapella,' and we were like, 'Oh wow!'"
