On The Rocks (OTR) is an international rock band formed by British, Dutch and Brazilian musicians with different musical backgrounds, leading to a unique style.
In May 2006, British singer John Lawton (ex-Uriah Heep and Lucifer's Friend) and Dutch guitar player Jan Dumée (ex-Focus) joined forces to create a new rock band that would combine their different styles in one strong new project, to be called On The Rocks or, more simply, OTR.
Together with Lawton and Dumée are Brazilian musicians Ney Conceição on bass, Xande Figueiredo on drums, and Marvio Ciribelli on keyboards. Their debut album, called "Mamonama", was released on October 10th, 2008.
