Richard David James (born 18 August 1971), best known as Aphex Twin, is an Irish-born British musician, composer and DJ. He is known for his idiosyncratic work in electronic styles such as techno, ambient, and jungle. Journalists from publications including Mixmag, The New York Times, NME, Fact, Clash and The Guardian have called James one of the most influential or important artists in contemporary electronic music.

Raised in Cornwall, James began DJing at free parties and clubs in the area in the late 1980s. His debut EP Analogue Bubblebath, released in 1991 on Mighty Force Records, brought James an early following; he began to perform across the UK and continental Europe. James co-founded the independent label Rephlex Records the same year. His 1992 debut album Selected Ambient Works 85–92, released by Belgian label Apollo, garnered wider critical and popular acclaim. James signed to Warp in 1993 and subsequently released charting albums such as ...I Care Because You Do (1995) and Richard D. James Album (1996), as well as Top 40 singles such as "Come to Daddy" (1997) and "Windowlicker" (1999); the latter two were accompanied by music videos directed by Chris Cunningham and brought James significantly wider international attention.
