A native of Texas, Roy Hargrove has been traveling the world since the end of the 1980s accompanying the most prestigious of musicians, such as Sonny Rollins, Herbie Hancock and Wynton Marsalis. Now leader of a quintet, future greats can't wait to play with him. In Vienne, he invites Mos Def, alias Yaslin Bey, a New York artist, to set the Théâtre Antique alight. It's an explosive collaboration between the Texan trumpeter's transcendent jazz and the cutting flow of the US rapper. Although his background is jazz, Roy Hargrove is a lover of soul, funk and hip-hop. Whenever a musician has appealed to him and whatever school of music he adheres to, Hargrove has arranged to play alongside him. And so R.H., the Texan, accompanied Sonny Rollins in 1991, Herbie Hancock and Michael Brecker on the album Directions in Music and recorded in Havana with the Cuban masters and, still later, with rapper, Common. More than any other today, Hargrove has that double culture of bop tradition and urban music.
