Easy peasy. First person posts the name of two bands (that's me).
Then the next person chooses the best (in their opinion) and pits them against another band.
Third person chooses the best and puts them up against another band and so on.
Don't have to be same genre, (helps if they are). . Everyone get it? Good.
So to start...
...The Beatles V. The Rolling Stones.
and for fu
cks sake, no arguing.
