In celebration of last week's deluxe re-issue of Eric Clapton's Slowhand album, Universal Music has created an app. The interactive Fender Tweed Amp allows you to explore the box set, as well as being able to listen to exclusive tracks from the Live at Hammersmith Odeon bonus concert disc. Slowhand was released in 1977 and was Clapton's most successful album of the decade, producing such classics as "Cocaine," "Lay Down Sally" and "Wonderful Tonight."
