A three-track sampler on the Bill Berguson Band website showcases the quartet’s tight, rock- forward sound: blazing guitar, wild organ and heavy drum work. The group leans into the experimental with two tight instrumentals and takes a critical look at modern-day work life on the song “I Will Be Free.” Band leader Bill Berguson is a straight-from-the-gut singer and has developed both a light touch and fire-wagon roar on the Strat. Multi-instrumentalist Mark Eskola shines on the keys but also contributes on the guitar and cello. Travis Hilton on drums and Chris Engstrom on bass hold down a solid-gold rhythm section.
