Fitting a squeeze-box Argentinian bandoneón – an essential element of tango dance-hall bands – into a classical-music milieu is a bit of a stretch. The two sound-worlds are so fundamentally different that it’s hard to imagine how they could intersect. Nonetheless, star Argentinian bandoneónist J.P. Jofre and the Santa Rosa Symphony gave it a whirl on Sunday at Weill Hall in Rohnert Park, premiering a concerto for bandoneón and orchestra by Pablo Ortiz, an Argentinian professor of composition at UC Davis.
