South African night trance (sometimes referred as SA trance or Twilight Psy) is a darker form of psychedelic trance music that started and is mostly produced in South Africa. Unlike the Russian and German dark psytrance, South African psytrance is more rhythmic with large percussion usage. It is melodic and danceable, yet keeps the nasty attitude. It is highly influenced by full on and tribal music, but not tribal or erratic enough to be classified as suomisaundi. Though South African Psytrance and suomisaundi may share similar styles, as both being the only psychedelic trance genre to combine tribal beats in its music, the genres are very different, South African Psytrance is well more dark and harsher, it still leans to european styled trance, while suomisaundi is less polished and more inspired by classic goa trance, also suomisaundi developed in an entirely different place, finnland rather than south africa. It is not uncommon to see musical groups of dark psytrance musicians with South African psytrance musicians or South African psytrance tracks in dark psytrance compilation albums, and vice versa. Also, there are artists such as Shift (Chris Hoy from Cape Town, although later leaned more to full on) who combine their music with dark, or releasing tracks along with dark or dark\full on musicians (such as Psychotic Micro). The "South African sound" is not made by South African musicians only, for example the Israeli duo Abomination, the only non-South African musicians signed in the Cape Town based record label Nexus Media.
