JD Twitch, the artist behind Optimo, is being honored posthumously with a charity cover of The Waterboys' 'The Whole Of The Moon' by a one-time supergroup called The Watergirls, and James Murphy contributed to the DFA Records release in tribute. His record collection is also set to be sold through World of Echo, while his DJ mix 'The Mix 123: Optimo' remains a notable release.
