Electric Masada last night

Anybody else catch the show at Tonic last night? It was my first time seeing them. They played hard, but they had a different line-up than usual - missing Medeski and with a young guitar player I'd never heard of named John D... something -- I didn't catch his name -- does anyone know who he is? I liked a lot of his playing, though I wish I knew what they sound like with Ribot. Somebody the other day mentioned a Miles electric sound, and I definitely heard that. I got the feeling they weren't in top form last night, maybe due to the new guitarist. Can any of you connaisseurs provide a broader perspective? Paul
