The unique duo Yesness, formed by Kristian Dunn (El Ten Eleven) and Damon Che (Don Caballero), came together through astute musical matchmaking. Within a year of their first virtual meeting, their nascent project’s debut record, See You at the Solipsist Convention, was complete. Scaffolded around eight-string bass, knotty percussion, and intricate syncopation, See You at the Solipsist Convention is a carnival of delights for fans of the post-everything persuasion—uncategorizable yet reverent to the altar of instrumental rock. “Nice Walrus,” a string-studded panorama featuring Joyful Noise labelmate Kishi Bashi, volleys between nervy hyperactivity and heartfelt grandeur.
