Ash Riser (born August 29, 1989), also known as 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 and hip hop music, among other genres.
