Most composers wouldn’t dare write a work for a horn, a violin, one cello, and TWO violas; fortunately for us, Mozart is not “most composers.” Natural hornist Elisabeth Axtell joins La Speranza for Mozart’s Quintet for Horn and Strings in E flat major, juxtaposed thematically with Mozart’s “Hunt” quartet. A string quartet written by Antonio Rosetti, Mozart contemporary and double bassist, rounds out the program.
