No I am not crazy and no I am learning the cello. If you don't know what a cello is, its the really big violin. if you don't know how it looks like it then look it up. I say its cool cause of the band Apocalyptica. Its a band that focus on using the cello and became famous on playing METALLICA songs. Rock and metal bands mostly use guitars, bass, and drums even a piano. But these guys use the chello. This I believe is new.
