For jazz pianist Lynne Arriale, melody is key. Whereas some piano players seek to impress audiences with endless virtuosic runs or tricky chord extensions, the Wisconsin-bred Arriale focuses on making instrumental jazz that sings. Maybe that’s why on her 2011 release, Convergence, Arriale covers some of the century’s most memorable pop and rock songs, including “Paint it Black” by the Rolling Stones, “Here Comes the Sun” by the Beatles, and “Call Me” by Blondie. In the process, she’s put together an impressive band that features young hotshots like Omer Avital, an Israeli bassist making waves in the New York music scene. In “Dance of the Rain,” the spotlight is on Avital, but not on bass: he’s playing the Arabic oud, giving a jazz treatment to an instrument usually reserved for traditional desert melodies.
