WHILE MY GUITAR APP GENTLY WEEPS: A new iPad app, The Guitar Collection: George Harrison, went on sale at the iTunes Store today, two days before the Quiet Beatle’s birthday. The app features a number of Harrison's best known guitars, including the Gretsch G6128 Duo Jet, the Gibson J-160E, the Rickenbacker 360/12 (pictured), the Fender Stratocaster named “Rocky,” the Ramirez Classical, the Fender Rosewood Telecaster and the Zemaitis Lotus 12-string. What’s cool about this app is that, , with the help of 360° imaging by photographer Steven Sebring, viewers can see the scratches, dings, and worn threads on the guitars, while Harrison introduces many of the guitars and plays sections of songs, thanks to his personal audio recordings. The video section contains footage of Ben Harper, Josh Homme, Mike Campbell and Dhani Harrison playing and showcasing the guitars and exploring their feel and tone. In addition, Conan O'Brien and Dhani discuss what make these guitars so exceptional, while Gary Moore shares his views on what made Harrison such a distinctive and influential guitarist. The app, created by Bandwidth Publishing, in conjunction with the George Harrison Estate, sells for $9.99 at the Apple App Store. You can watch a video preview here. (2/23a)
