Ash Winston Riser (born August 29, 1989), also known by his former stage name Ashtrobot, is an American recording artist and music producer from Los Angeles, California.
He embarked on his music career when he was 15 years old, forming a rock band called Pistol Pistol (stylized P!stol P!stol). Due to differences between members, the band broke up in 2009 and Riser subsequently began to put his focus on music production, fusing Electronic, Hip Hop, and Rock music amongst other genres. Riser later began working with longtime friend, Derek Ali (Mixed By Ali) of Top Dawg Entertainment, who introduced him to rapper Kendrick Lamar, with whom he heavily began collaborating with. Riser then signed a record deal with Israeli music producer Borgore's label, Buygore and released music alongside some of EDM's hottest acts.
As of 2018, Riser has founded a label, Bennu Records, out of Los Angeles, California. The first album release on the label comes with Riser's upcoming album, Howl, available everywhere 11.9.18.
