Thai guitarist D Gerrard's cool, jazz-inflected R&B encompasses a range of soulful sounds. His loose, improvisatory tone is reflected by Bobby Caldwell's smooth jazz, while Jamiroquai's acid-funk anticipates his groove-oriented tempos. And Gerrard is known to drop a rhyme or two, a habit that may be inspired by hip-hop greats like Ice Cube and The Notorious B.I.G.
