Although the members of Masked Intruder keep their identities hidden under ski masks, the mysterious band's sugary sweet pop-punk shows that they wear their hearts on their sleeves. Calling Madison, Wisconsin, home, the quartet rose in the early 2010s, label-hopping between Red Scare and Fat Wreck for their first two LPs, which were interspersed with a healthy number of EPs and split singles. Eventually settling in with Pure Noise Records, they returned with the Billboard-charting III in 2019.
