When this alt-rcok band first formed in Buffalo in 1986, its music sounded harsher, perhaps reflecting the city that band members called home. The group would eventually refine its sound and go on to sell truckloads of albums in the '90s when it delivered radio Top 10 radio hits, including "Name," "Slide" and "Iris."The veteran alt-rock band performs tonight at 7 at Blossom.
