Meet JamBlaster: a smartphone accessory for musicians that lets you play live, in sync music with others remotely. You will be able to broadcast live video performances, teach or take lessons, and record high quality audio. Band members can use such a solution to rehearse without needing to find space or travel.
Thanks to JamTracks, you will have access to a ton of songs to learn and play along. The device is compatible with iOS and Android devices. You can find out more here.
