All Along the Watchtower Performed Solely by iPhone Apps

An anonymous collective of coders and instrumentalists recorded this version of “All Along the Watchtower” — which admittedly is more of a cover of the 1968 Jimi Hendrix version of the song — and sent it to Evolver.fm. The project was spearheaded by developer Adil Sherwani, who created the Guitarism App that simulates the experience of strumming away on six strings using any Apple smartphone, music player or tablet. Sherwani performed the vocals himself, singing directly into an iPhone without employing a external microphone. Although the constituent parts were mixed together using desktop Macs — ostensibly because the ‘band members’ were scattered all over the place — 100% of the resulting music was created by smartphone apps.
