In 2011, she started recording music and her demos eventually made their way to rapper Kanye West, who flew Bruno to London to write with him and the G.O.O.D. Music camp. She wrote and played piano on “The One,” (West’s 2012 Cruel Summer G.O.O.D. Music compilation album), landing Bruno her first song placement.
She relocated to Los Angeles in 2013 and in less than two years, Bruno signed her first recording deal with Atlantic Records. In 2015 she collaborated with GTA and Skrillex on the EDM classic, "Red Lips," before entering the spotlight as a solo artist with her debut single, “Search Party,” which led the soundtrack to Fox Film's ‘Paper Towns.’
In 2016, she delivered “Tip Of My Tongue,” which was featured in the Apple Watch Series 3 commercial ad campaign. In June 2017, Bruno released her debut EP, “I AM SAM PT. 1,” with “Hello Hater” as the lead single, along with "So What," featuring Rockie Fresh. In 2018, Bruno teamed up with Jaykode on his hit single, "Careful."
Bruno has written for Britney Spears, Lady Gaga, Icona Pop, Nicki Minaj, and Eminem, among other artists. She wrote and produced the song “Famous” on Lil Wayne’s much anticipated album, ’Tha Carter V,” which was released in September 2018.
