M.Shadows to guest on SOAD's John Dolmayan new album

M.Shadows is set to provide his vocals to a track on System Of A Down drummer John Dolmayan’s new project These Grey Men, which is set to be released “within the next four months”.

Speaking of the album – of which System’s own Serj Tankian also guests – John tells SOADMexico: “There’s some cool artists on it. Serj sang two songs. The Avenged Sevenfold singer – I don’t know if you know Matt, he’s fantastic. Really nice guy, by the way, and he sang a song.”
