Actor and comedian Bill Murray met German cellist Jan Vogler on a trans-Atlantic flight. The two struck up a friendship and soon had the idea to work together on a project: New Worlds. On the album and in live performance, Murray as both brings his charm and wit to songs by Foster, Gershwin and Bernstein. He also narrates readings of classic American poetry and prose by Whitman, Hemingway, Twain and others, in dialogue with Vogler’s singing Stradivari cello. They are joined by violinist Mira Wang and pianist Vanessa Perez.
