About the Show


Spectrum was voted Best of Las Vegas for two consecutive years. This award-winning tribute show to Motown and R&B ran for 4 years in succession on the Las Vegas Strip. Now touring the globe and available for your event.

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 award-winning group Spectrum, which draws upon the talent of four radiant voices and diverse personalities to form a first class vocal quartet. 

In 2009 Spectrum was selected to receive the Vegas Entertainment Consumer’s Living Legends Award for Excellence in Entertainment.

On April 28, 2012 Spectrum joined the ranks of Las Vegas Legends Wayne Newton, Frank Sinatra, Sammy Davis Jr., Liberace, Rich Little, Siegfried and Roy, Elvis and many more when they were awarded the 68th Star on Las Vegas’ Walk of Fame.

About Spectrum

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 and Australian tours, 100’s of headlining  performances aboard Royal Caribbean, Princess & Norwegian Cruise Line  ships, a Doo-Wop to Soul Review at the Hollywood Palladium, as well as more than 100 performances with 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.

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!
