Twilight Zone was the second single released from 2 Unlimited's debut album Get Ready! in January 1992.
The UK release of the single was the first 2 Unlimited single in that country to include the vocals of Anita Doth as they had not been featured on their debut hit "Get Ready for This". However, Ray Slijngaard's raps were once again removed. The instrumental version of the track sounds different from the original version. It's in a more Hi-NRG style with more bass and added cowbells.
The release scored chart success in many European countries and topped the chart in The Netherlands. Twilight Zone was the second single in a row to just miss out on the top spot in the UK again peaking at number 2. It was 2 Unlimited's biggest hit on the U.S. Dance chart reaching number 5.
The song has become a staple of National Hockey League teams, as many of them play an instrumental loop of the song during games. Its popularity in the NHL may have been inspired by Ray Slijngaard wearing a Los Angeles Kingshoodie in the music video. It has also been used in NHL 11's EA Trax.
Following the bleak success of the "No Limit" single came the "Twilight Zone (Millennium Remixes)". It had the same success as its predecessor, although the remixes were more commercial and radio-friendly. It received good airplay in Europe but had very little success in the charts.
