Welcome, always cool to meet a longtime J Mascis fan 
No news on tour dates yet, but like SG said, check back often for tour dates, they pop up out of nowhere sometimes :aliensmile:
In the meantime, you can download some great shows of J/Dinosaur Jr at FreesoFree.net.
Theres a couple recent shows, J Mascis & The Fog live & sonic @ Slims, acoustic performance from the recent Autism benefit in Mass & all kinds of other shows Freaks from all over the world have made available. Huge thanks to Anthony for hosting & making all those shows available for the Freaks out there
