Re: Creating music as a drummer?
You should definetly learn more than one instrument. The only problem as everyone on here demonstrates is which one! Pianos and keyboards allow you to play chords and melodies at the same time. However i would go with the guitar, it sounds like you already know the basics and you'll get a much better idea of what the guitarist in the band can play and the sorts of things you can do on a guitar like harmonics and vibrato and stuff.
