Matheus Zerbini Massa (born 25 December 1997), known professionally as Zerb, is a Brazilian DJ and record producer.
In 2012, at the age of 14, Zerb became interested in electronic music. Inspired by DJs like Skrillex and Deadmau5, he began producing his own songs and releasing them on his YouTube channel and SoundCloud. Initially, his productions contained elements of progressive house and big room.
He is currently part of the event agency and production company Plus Network. Zerb achieved his big international breakthrough in 2023 with the song Mwaki together with the Kenyan singer Sofiya Nzau, in which the lyrics are written in Kikuyu. The track went viral across various websites, including TikTok, and reached the charts. The song, whose title means "fire" in English, has been remixed by artists such as Major Lazer and Tiësto. In January 2024, the video for the song was shot in Kenya's Hell's Gate National Park.
