The Litmus Green formed in 1991 from the ashes of a band called Media Children, of which Rev. Sean, Ed, and Rick were members and Mateo was a friend / roadie / groupie. When things got too heavy and serious between the members of MC they broke up; since Mateo was already playing bass for a side project called Aftermath with Ed and Rick it seemed only natural to form a band with Rev. Sean on vocals. The rest, as they say, is a gross miscarriage of justice against humanity.
