LMHR was set up in 2002 in response to the perceived increase in support for the far rightBritish National Party. The first big LMHR concert was a festival in Manchester’s Platt fields, headlined by Doves and Ms. Dynamite. The organisation believes that modern music is influenced by many cultures and traditions, and that it can be used to bring different kinds of people together. Most LMHR concerts include several music genres.
In October 2007, popularity for the group dramatically increased following a big campaign in the music magazine, NME.
