With support from Third Eye Blind and Arizona, Florida’s alt-rock Yellowcard—still with violin—is fresh off its collaborative album (A Hopeful Sign) with Tennessee’s post-rock duo Hammock wherein new versions of Yellowcard favorites are reconfigured in an ambient strangeness. Hatched in the ‘90s, they recently took six years off and feel it was a “transformative resurgence.” That’s alt-speak for “we were bored” but early returns from the tour that started last week in the Pacific Northwest has them sounding better than ever.
