Mike Portnoy will be drumming for Avenged Sevenfold for their upcoming tour. He did the drum tracks for the new Avenged Sevenfold album. Mike said
though I wish I could stay on board with A7X in a more permanent capacity, the reality is that I am committed to Dream Theater as my main priority (that is my baby after all!), and I will need to resume work with DT to start a new album at some point in 2011….
