Joburg's eclectic soul trip group The Muffinz have been added to the line-up for the Red Hot Chili Peppers concert in Joburg only, performing along with Die Antwoord on Saturday, 2 February, 2013, at the Soccer City Complex, FNB Stadium, Joburg.
The Muffinz began in 2010 when Mthae, Simz and Atomza met while singing in the University of Johannesburg choir. They decided to call themselves The Muffinz. Mthae explained: "We wanted a name that would be remembered, something catchy, but a name that people would want to find out more about. Plus, we all come from different backgrounds musically and so we all bring different ingredients - as in the ingredients in a muffin." By April 2011 Skabz and Keke had joined the band and they found a residency in the suburb of Melville. They released their debut album in May 2012 called "Have You Heard?" produced by Robin Kohl, Tebogo Moloto and Leroy Croft.
Red Hot Chili Peppers have sold more than 60 million albums, including five multi-Platinum LPs, and won six Grammy Awards, including Best Rock Album for "Stadium Arcadium", Best Rock Performance By a Duo or Group for Dani California, Best Rock Song for Scar Tissue, and Best Hard Rock Performance With Vocal for Give It Away. The band holds the record for the most number one singles of all time at Alternative radio, a total of 11, and a combined 81 weeks at number one . They have also won 8 MTV Video Music Awards. In April 2012 the band were inducted into the Rock and Roll Hall of Fame.
