Mau5ville: Level 1 (stylized as mau5ville: Level 1) is an extended play (EP) and compilation album by Canadian electronic music producer Deadmau5.[1][2][3] It was released on July 13, 2018, through his record label Mau5trap.[4] The release features "Monophobia", a collaboration with Australian singer and musician Rob Swire, with remixes, as well as original songs by DJs Getter and GTA.[5] Two follow-up EPs, Mau5ville: Level 2 and Mau5ville: Level 3, were released in November 2018 and February 2019 respectively.
Mau5ville: Level 1's release date was first revealed through various store pages on July 3, 2018.[6][7] The cover art was also uploaded to Deadmau5's Twitter account.[8] However, the EP was officially announced on July 12, 2018, the day before its final release on July 13, 2018, which is, coincidentally, Zimmerman's name day.[9] The Beatport exclusive version of the EP was released with two additional bonus mixes of "Monophobia".[10] The EP is named after Deadmau5's former online server on the sandbox video game Minecraft.[11]
The opening track, "Monophobia", serves as the return of long-time collaborator Rob Swire from Pendulum and Knife Party, who had previously collaborated with Deadmau5 on his song "Ghosts 'n' Stuff" in 2009.[a][12] The song was also remixed by other artists who have released on the record label Mau5trap, including producers Attlas, Latroit, and Rinzen. A music video for "Monophobia" was released on Deadmau5's YouTube channel on July 16, 2018.[13][14]
