Nashville band Steelism may be a new name to some listeners, but Spencer Cullum (steel guitar) and Jeremy Fetzer (guitar) are probably familiar faces. The two musicians met in Nashville performing with bands ranging from Caitlin Rose to Andrew Combs to Wanda Jackson,. Their recent release 615 to Fame has been lauded for its innovative instrumental tracks, but their live show is where the duo (along with whatever cast of Nashville talent happens to be backing them at the moment) shines: just try to get through a performance from Steelism without dancing a little, we dare you.
