A very in-depth interview, though no Symphony X news, with Russell after the TSO tour last month:

It's a really great read. He talks about the PTSD of dealing with touring again after the Adrenaline Mob crash last summer. Also, apparently there were a few shows at the very end of the tour where one of the female singers became ill and Russell had to fill in on one of her songs:
That may be the single purest, most perfect Russell Allen performance I've ever seen. He was feeling every second of that song. Good God.
