Bands really just don't start, they evolve. Usually a couple people get together and jam. If there is any chemistry, They may start asking around for usually a drummer or bassist or keyboard. Then if the people can find a common goal; walaaa a band.... girls, money, record contract, fame, concerts, SUPERSTARDOM!!!!! It's easy!!!
Forgive my sarcasm. Just find other musicians you like to be around and have fun. If it's ment to be [the band] ; It will be.
Peace my brothers!! Do It NOW!!!
