Evan Yi, known professionally as YAYAYI (recently known as ATIVAN COREA) is a mysterious hip-hop producer currently based in Los Angeles. He is known mainly for his work with hip-hop collective H20$$$SPORTS$$$, and their SoundCloud account which has been active since 2011. In 2009 he started releasing beats under the name Evany, and continued releasing music under the alias up until late 2010. On September 16th, 2011, YAYAYI released the song "[][][][][][][][][][][][][[][][][][][][[][[[][]][[][][][][]][]][][][][][]][][]][][][][][][][][]][]][][][]. PART333% yayayayay original is 333% of this. ya feel me bitch. pornstars gone hate amateurporngodcummingsoonkoreanroomsalon." on a new SoundCloud account, which was the first song released under the YAYAYI name (at the time stylised as "\/ /\ \/ /\ \/ III ///"). The song was met with acclaim, and it quickly became a fan favourite among SoundCloud users.

Recently, a sample of "\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ 6" off of YAYAYI’s acclaimed self-titled album has gone viral on TikTok. However, the track's virality has brought more attention to the person that looped the sample rather than YAYAYI. The track, which is now labeled as "uhh" has over 80 million streams on Spotify.
