Some of the coolest apps for iPads and iPhones turn them into virtual musical instruments like keyboards and guitars, so it was only a matter of time before someone put together an orchestra with a bunch of Apple instruments playing together.
Behold the first Christmas concert by the North Point Community Church iBand, from Apharetta Georgia. In the video they rock a Christmas medley using only iPad and iPhone based virtual instruments, including drums, bells, guitar, synth, and percussion. They save the best for last, with an awesome version of Feliz Navidad complete with a hideously auto-tuned vocal performance.Via Gadget News
