Matthew Lee, better known as Gammer, is a DJ and producer from the UK. First coming to prominence within the UK melodic hardcore and hard dance music scene, he has since branched out into all genres of dance music.

Gammer is perhaps best known for “THE DROP”, which has been played out in sets all over the world. He owned his own record label, Together We Rise, for a couple of years, but now primarily releases music through Monstercat.
