Harmonix and MTV Games have announced the addition of seven new tracks from progressive rock band Rush to the Rock Band Music Store catalog of downloadable content for the Nintendo Wii.

The lineup features master recordings from Rush's most successful album, Moving Pictures, including "Tom Sawyer," "Red Barchetta," "YYZ" and "Limelight." Other tracks include "The Camera Eye," "Witch Hunt" and "Vital Signs."

This week's offering comes from the Rock Band Music Store already released to owners of Xbox 360 and PlayStation 3. Wii fans can expect a rollout of the previously released downloadable content until the entire back catalogue of more than 550 songs is available.
