This band was come up with the novel idea of having a new fan play keys for them at each location in their tour. They put song transcriptions on their website for fans to download and then choose someone to play live at a gig with them! Saves hiring a keys player :)
Maybe not the best idea if your band anything like MUSE or Ben Folds where your piano parts have finger flying all over the place but for a pop rock band like this it's ideal. Innovative, daring and fun. Thumbs up.
