Health Struggles and Departure from the Band
Following the release of their second album, Cavalcade, in early 2021, Kwasniewski-Kelvin took a hiatus from the band, citing mental health concerns. He expressed hope for a return, with support from his bandmates, who emphasized the importance of mental health awareness.
