Feedback is a studio release by the Canadian rock band Rush, released in 2004 with eight cover songs. It is less than half an hour in length, and the fan community was told it would be released in the US with an EP-appropriate price of $9.95. It was however priced at $14.99 when it came out in stores. The CD's release marked the 30th anniversary of the release of the first Rush album. Its single, Summertime Blues, was the official theme song for the WWE's SummerSlam 2004 PPV event. The tour following the album was called the R30: 30th Anniversary Tour. This yielded a moderately successful live album and DVD, setting a trend for official live releases from each tour, which the band has continued through the present.
