The managers of the Iroquois Amphitheatre are doing everything they can to put the facility to good use and with the help of Production Simple, the concert count is steadily growing. On that list will be a June 25 show by California's Counting Crows, a band that, while not exactly a jamband, is very focused on performance and after a twenty-one career, have gotten reasonably good it. There is also that little trick that singer songwriter Adam Duritz does of rewriting and extending the songs, so that every show is individual, even if the setlist is the same. They have have a new CD, the just-released Underwater Sunshine, which is, amazingly, only their sixth studio album. Filigar and Good Old War open.
