South African rock act Prime Circle released their fourth studio album Jekyll & Hyde, via EMI in September 2010.

The album spawned the legendary single, Breathing, which reached No. 1 status on radio stations nationwide. Singles Never Gonna Bring Us Down and Turning In My Sleep and Turn Me To Stone received high rotation allowing the album sales to soar.

Jekyll & Hyde entered local sales charts at No. 1 reaching Gold status within two weeks of its release. To date, it has gone Platinum and now remains the second highest album for Prime Circle, after All Or Nothing.

Recorded and produced by Theo Crous at Bellville Studios in Cape Town, South Africa, the album was mixed in Los Angeles by Kevin Shirley, who has previously worked with the likes of Aerosmith, Iron Maiden, Silverchair and Journey. New York-based Sterling Sound mastering engineer George Marino, who is famed for his work with Guns ‘n Roses and Ozzy Osbourne, laid the final touches on Jekyll & Hyde.

The album Jekyll & Hyde earned the band a slew of SAMA (South African Music Award) nominations in 2011, giving them six nominations and one win in this year.

The first two singles from the album, power ballads Breathing and Turning In My Sleep, were each nominated for the SAMA MTN Record of the Year in the year of their release.

In March 2011, Prime Circle won the Best International Breakthrough Act at the MK Awards (MK was the leading South African alternative music channel at that time). The awards were distributed based on fan votes.
