Anyone who listened to country music in the late '60s and '70s certainly needs no introduction to Glen Campbell. But it's been 14 years since his last studio album. Now, at 72, Campbell proves he's no variety-show relic. Pulling a Johnny Cash, he covers both classic rockers (John Lennon, Jackson Browne) and contemporary ones (Green Day, Foo Fighters) with his fresh-again style. The highlight is his version of Travis's "Sing," which shows that the Rhinestone Cowboy remains in strong, robust voice after all these years.
