Born in 1987, Icelandic composer Olafur Arnalds has embraced the twittering age wholeheartedly. He recently recorded seven songs in seven days (one song per day), and released this series titled Found Songs immediately to the public via Twitter in April. A believer in mixing the classical, contemporary and pop genres, Arnald’s mission is simply to bring his love of music to all walks of the musical world. With sold-out performances at London's noted Barbican Hall and invitations to tour with the progressive Icelandic band Sigur Ros, it seems like he's doing just that. Also tonight, music of Abbey Lincoln and Terry Riley.
