Free music (it's a genre) at Bourbon Street! Freely improvised music that gets rowdy. END TIMES TRIO is Springfield's only known avant-garde jazz ensemble. The group features Frank Trompter (Frank Trompeter Quartet, elevator_shoe) on tenor, alto and soprano saxophones, celebrated composer Mark Schwartz (Demons on Wheels, Tin Ghost) on bass and prepared guitar and Richard Gilman-Opalsky (Fire & Flux) on drums and percussion. They play dynamic improvised “art music” that treads a sonic terrain from sparse and melodic to dense, blustery cacophony. Their music is generally unstructured, lacking pre-arranged song forms, planned melodic lines and predictable rhythm.
