One of the best trumpeters to arrive after Wynton Marsalis, the 45-year-old Roy Hargrove has an affinity for sharp but husky melody, carried across genres. In his old band Crisol, he offered a modernist’s approach to Afro-Cuban jazz. In the group RH Factor, he explores the boundaries between jazz, funk and hip-hop. He’s back at Blues Alley this week with his quintet. Two separate sets each night at 8 and 10 p.m.
