December 2009 saw a further advancement in the band's history with the creation of a second contesting band, known as Melingriffith 2, or M2 for short. Twenty eight players turned up for the first rehearsal and by mid-January 2010 all positions were filled. Dewi Griffiths, Principal Cornet with Tredegar Town Band, was appointed to the post of Musical Director, and he soon had the band playing together as a cohesive unit.
Entering the Welsh Regional Contest in March 2010, their first ever competition, M2 gained a creditable fifth place in the Fourth Section. Returning in 2011 they succeeded in winning that contest, gaining a place at the National Finals.
From 2012, they were promoted to Third Section nationally. The band then progressed to be graded nationally in the second section, and although this seemed a formidable challenge, the band again gained an invitation to the National Finals in Cheltenham in 2013, having been runners-up in Swansea.
The original band, now known as M1, were placed fourth in their first attempt at Section One in the 2010 Welsh Regional Contest, but won a place at the 2011 Finals with a creditable second place at Swansea in March 2011. With this came national promotion to the Championship Section from 2012.
