Fans of the “Quiet Beatle” will get another chance to hear him play. An iPad app that examines Harrison’s music and guitars, and contains interviews with the musician, was released Thursday on iTunes.

The app was created by Bandwith Publishing with the help of Harrison’s estate and his son, Dhani. He appears in the video, along with Ben Harper, Josh Homme, and Mike Campbell, who play and showcase the guitars. In an interview with the New York Times, Dhani Harrison said that it’s important for fans to hear the guitars, rather than just see them.

“Paintings should be in museums and should be able to be seen,” he said. “Instruments should have to be played every once in a while. Otherwise they’ll perish.”

Wired notes that the collection includes the 12-string Rickenbacker 360/12 that opened and closed The Beatles’ “A Hard Day’s Night” and the Gretsch Tennessee Rose that Harrison played during the band’s 1964 Shea Stadium concert.

Comedian Conan O’Brien also appears in a video to discuss the guitars with Dhani. The app is expensive, at $9.99, but with such an extensive archive, it’s more like a multimedia book.

Last year, fans mourned the 10th anniversary of Harrison’s death with concerts and candlelight ceremonies. He would be turning 69 on Saturday.
