Another group of young musicians known as “Young Lions” or “New Traditionalists” continued to draw inspiration from former traditions, merging concepts from bebop, cool, and hard bop with their own innovations. Roy Hargrove in “Proclamation” (1989), along with Terence Blanchard, Marcus Roberts, Jeff Watts, and Christian McBride, are a part of this group. With yet other aspirations, Wynton Marsalis continued his mission to preserve the nation’s jazz heritage through his work with Jazz at Lincoln Center, which he co-founded in 1987. In 1991, he became the artistic director of the Jazz at Lincoln Center Orchestra, organized in 1988. His focus on the classic repertoire from the pre-1960s eras and the exclusion of avant-garde, free jazz styles, and more contemporary expressions has generated some criticism.
