The Red Hot Chili Peppers are one of the most successful and influential American rock bands of the past 25 years. They have sold around 60 million records worldwide, and have influenced countless subsequent bands. They formed in 1983 in Los Angeles, California, and started out as a funk rock outfit. Their reputation was built around some awesome live shows, and this red-hot outfit became noted for its outstanding musicianship. The first four albums sold reasonably well, with each one outselling the last, but the band's popularity truly exploded in 1991 with the release of Blood Sugar Sex Magik. The album brought a hard rock edge to their funk sound, whilst the acoustic ballad Under The Bridge, which was unlike any previous material, became a huge hit worldwide, and launched the Chili Peppers into the mainstream. The album has now sold in excess of 13 million copies worldwide. 1999's Californication marked a drastic change of style. Whilst the music still had a strong funk element, singles such as Scar Tissue and the title track demonstrated their move towards a more melodic, mellow, radio friendly pop rock style. They have continued to produce excellent, melodic alternative rock, and are rightly regarded as one of the best live bands on the planet.
