Dennis would soon hook up with David Bowie for Bowie's "Young Americans" album, the album that would give Dennis the opportunity to play not only with Bowie, but with John Lennon. Whirlwind World tours playing with Bowie would soon follow, and Dennis was a huge part of Bowie's legendary "Berlin Trio" of albums (Low, Heroes, Lodger) that were considered Bowie's most brilliant and creative works. Stints with George Benson would follow before Dennis hooked up with Stevie Wonder in 1979 for studio and live work. A funny story about this is that when Stevie called Dennis for the gig, Dennis had no idea he was talking to Stevie Wonder, as Wonder used his real name (Steveland Morris) when making the initial call. Imagine Dennis' delight when he realized who Steveland Morris actually was! Dennis continued a great working relationship with Roy Ayers throughout the years, and in 1991, Dennis joined up with Roy's band full time for studio work and tours, a position that Dennis still proudly holds today. Between multiple world tours and albums with Roy, Dennis has quietly began piecing his own album together over the last few years, and this spring, Dennis finally put the finishing touches on his first official solo album, entitled "The Groovemaster". Dennis still lives in his native New York city, still busy with local gigs and other studio work. Dennis album is proudly dedicated to his four children, Darien, Naoto, Erika, and Kaito.
