Stampeding its way through Brighton, Mammothfest is the city’s only annual heavy metal festival and it attracts many crowds every year. It was first held in 2009 and since then it has grown in popularity and attracts large crowds of metal fans, welcoming huge names from the metal music community.

Mammothfest has two commitments: to offer the South of England the biggest hard rock and metal open air festival there is and to provide local, aspiring bands and musicians with the springboard they need to play amongst the stars and begin to make a name for themselves.
