Richard David James (born 18 August 1971), best known by his recording alias Aphex Twin, is an Irish-born English electronic musician and composer. He is known for his influential and idiosyncratic work in electronic music styles such as IDM and acid techno in the 1990s, for which he won widespread critical acclaim. He is also the co-founder of Rephlex Records with Grant Wilson-Claridge.
Initially releasing acid house and techno music as AFX, Polygon Window, and other aliases, James first received widespread acclaim for his 1992 album Selected Ambient Works 85-92 and his subsequent 1994 release Selected Ambient Works Volume II. He rose to mainstream popularity with his 1997 EP Come to Daddy and his 1999 single "Windowlicker". After a period of relative inactivity following the release of his 2001 album Drukqs to mixed reviews, James returned in 2014 with a new album titled Syro, which won him a Grammy Award for Best Dance/Electronic Album.
