 At the same time, computers facilitated the use of music "samples" and "loops" as construction kits for sonic compositions.This led to a period of creative experimentation and the development of new forms, some of which became known as "electronica".Electronica currently includes a wide variety of musical acts and styles, linked by a penchant for overtly electronic production; a range which includes more popular acts such as Björk, Madonna, Goldfrapp and IDM artists such as Autechre, and Aphex Twin to dub-oriented downtempo, downbeat, and trip hop.
