“In my fantasy world,” he adds, laughing, “I’ve been in the Kronos Quartet for 30 years. Wiancko, also a composer, joined Kronos in February of this year. “I grew up with the Kronos Quartet,” cellist Paul Wiancko says in Green’s film. And hundreds of musicians, alone and in groups, have eased through doors kicked down by Kronos as it addressed diversity, inclusion, and iconoclastic funkiness with programming, presentation, and promotion. …t’s not that big a stretch to suggest the new-music world falls into two eras: “Before Kronos” and “Because Kronos.” Hundreds of pieces have come about through Kronos commissions, boosting the careers of hundreds of composers.
