In 2013 Shelton conceptualized a never before platform, Concert Pitch, for amateur musicians to exhibit their skills. Held every Thursday at the Rosary Church - Souto Maior Community Centre, Caranzalem, amateur musicians were provided with a stage, equipment, instruments, accompaniment and an audience to perform. These were non- competitive events where everyone went home a winner. Dozens of musicians and singers took part in these well attended and lively evenings and gained the confidence to perform in front of a live audience. In between performances the audience was kept entertained with music related quiz questions involving participation from non- musicians as well. Professional musicians also performed as guest artists to motivate the novices.
The huge success prompted Shelton to continue Concert Pitch in 2014.
