Between songs, lead vocals trade barbs with the audience—wry asides, surreal observations, and the occasional sideways compliment. There’s a communal sense to the evening: people who know the words sing loudly, those discovering the band for the first time nod and grin as if let in on a secret. Loossers seem to enjoy that exchange, coaxing crowd noise like a second instrument, letting applause and laughter feed back into the set.
