Webster defines Spectrum as a "series of radiations arranged in regular order" or a "continuous sequence or wide range". This could not be a more appropriate description of the group Spectrum, which draws upon the talent of four radiant voices and diverse personalities to form a first class vocal quartet. After spending six stellar years recreating the sound and style of the Four Tops in Las Vegas' multi-million dollar production shows American Superstars and Legends In Concert, the group has developed the versatility to credibly cover the music of groups from the Platters to the Temptations to Boyz 2 Men. It is this versatility that has propelled them to the status of headlining their own shows in which they perform stirring renditions of the all the best cover tunes. In addition to regular corporate and private parties, Spectrum’s credits include European tours, headlining aboard Royal Caribbean, Princess & Norwegian Cruise Line ships, a Doo-Wop to Soul Review at the Hollywood Palladium, as well as performances with over 40 symphony orchestras throughout North America. Voted Best of Las Vegas in 2005 and again in 2006, their award winning show ran for 4 years in succession on the Las Vegas Strip, ending only when the Mirage-MGM owned property that housed it closed its’ doors. In 2009 they were selected to receive the Vegas Entertainment Consumer’s Living Legends Award for Excellence in Entertainment. Spectrum performs in Las Vegas, throughout the nation and around the globe. Check their website for scheduled performances. Spectrum's credentials, collectively and/or individually include starring in no less than six major production shows, on the Las Vegas Strip and internationally; appearances on numerous television shows as special guests including the Today Show; featured appearances in motion pictures; starring roles in equity theater; special appearances at professional sporting events, (National Anthem); performing/recording with or opening for artists as varied as Tony Bennett, the Temptations, Blue Magic, Little Richard, the late Marty Robbins, the Platters, Frankie Lymon’s Teenagers, Doc Severenson and Fat Larry’s Band, to name a few. The group boasts four incredible singers, each with the voice of a solo artist, who combine their voices and dexterity to create the angelic harmonies and deft choreography that have become trademarks of Spectrum. The members of Spectrum consist of master recording artist Darryl Grant of Oakland, California, Chicago-born musician and versatile entertainer Pierre Jovan, David Prescott the silky-smooth, soaring-voiced first tenor from Rochester, New York and lastly, singer, actor and group founder Cushney Roberts, from East Orange, New Jersey, who left the life of a Princeton-educated corporate engineer and cut his teeth in the casino lounges in route to becoming a well-respected Las Vegas showroom entertainer. Let's just say this is a group of well-mannered, college-educated, world-traveled veterans of the entertainment business, who will entertain you!
