Tonight, Sonic Youth’s Thurston Moore made his second late-night appearance in support of his new Beck-produced solo record, Demolished Thoughts, taking “Benediction” (the song that was once the LP’s title track) to the Late Show with David Letterman. Performing alongside harpist Mary Lattimore and violinist Samara Lubelski, Moore brought his lovely ode to nuanced romance to the Ed Sullivan Theater, complete with lightly brushed drums and interwoven acoustic guitars.
