Roberts range, power, expressiveness and deadly accurate ears make him that rare singer who is equally adept at both breathtaking lead vocals and arranging and performing tight, crisp background vocals. In addition to being a top call session singer for two of the biggest advertising contractors in L.A., Robert recorded his own album on MCA Records, writing a large percentage of the songs himself.

Etta James was a strong vocal mentor to Robert, encouraging him to sing with her in all their live performances over a period of fifteen years. He handled both lead vocals and high harmonies on numerous tours and recordings for Frank Zappa, including an iconic reworking of the classic Allman Brothers anthem, Whipping Post. He also sang all the high harmonies on tour with Michael McDonald, combining with Michael’s range and power for the top end of a tight, soulful vocal ensemble.
