Details: Bernstein first saw the late, great New Orleans pianist Henry Butler play in 1984. "He was genius-level brilliant, man," he says, still marveling. "I couldn't believe there was a guy who could sound like the most ancient music and the most futuristic music at the same time." (Which is an apt description of Bernstein's music too.) Fourteen years later, Bernstein took Hal Willner's recommendation and hired Butler to play in the touring band that played the score for Robert Altman's film Kansas City. In 2013, the two musicians formed The Hot 9, the name a tip of the fedora to Louis Armstrong's landmark Hot Five and Hot Seven sessions of the 1920s. They released the acclaimed Viper's Drag album the following year, and toured until Butler's untimely passing in 2018.
