On Space, Time, Continuum, an eight-piece program, Diehl assembles a pan-generational ensemble of masters. Joining his core trio of bassist David Wong and drummer Quincy Davis, in different configurations, are the iconic tenor saxophonist-composer Benny Golson and the magisterial baritone saxophonist Joe Temperley, both 85 years young; the 39-year-old underground tenor saxophone giant Stephen Riley; and the rising star trumpeter Bruce Harris, not yet 30.
