Marian Hill wrote "Whisky" in the spring of 2013 and sent it to dozens of blogs hoping to catch some attention. The song created a buzz, and the following year, the duo released their first EP, Play, as well as a 7" single, "Lips." They received mainstream exposure when Romanian pop star Inna credited them as co-writers of her song "Diggy Down," which incorporated the hook of Marian Hill's "Got It." The pair signed to Photo Finish/Republic Records in early 2015 and released Sway, a seven-track EP.
In 2016, the duo issued their full-length debut album, Act One, featuring the number 21 single "Down." The LP reached number 42 on the Billboard 200. Their remix of Billie Eilish's single "Bellyache" appeared in 2017. Early 2018 saw the release of the punchy single "Subtle Thing," followed by an appearance at that year's Coachella Festival. Marian Hill's second long-player, Unusual, arrived in May 2018 and returned them to the U.S. albums chart as well as charting in France. August 2019 saw the duo issue the single "Take a Number," which featured a guest spot from Moroccan-American singer, songwriter, model, and activist Dounia. The song appeared on Marian Hill's self-released 2020 EP Was It Not. After collaborating with Roman Kouder on "Bonjour," they released "oOo that's my type" with Yung Baby Tate in 2021. This was followed by additional singles "omg" and "it never ends." ~ Paul Simpson, Rovi
