Following his treatment for throat cancer, Mark Karan is back in good health and on the road with RatDog. To mark his return, the guitarist will be the subject of our latest Jambands.com reader interview. So please send along any questions you may have for Karan. You may direct your queries to [email protected] (you have until the end of the day today). Our current Jambands.com reader interview with Jimmy Herring (who sat in with Karan and RatDog last week) is now up on the site.
