Alexmusic started out as a grindcore outfit, developing their sound with each album, with later albums often described as noise rock. In 2018, Alex signed to Ipecac Records and released the album Yummy Food, which released to universal critical acclaim, with many critics naming it one of the best albums of the year. It marks a significant departure from the artist's earlier style. Alexmusic's early material was primarily described as grindcore, while their later material has been described as noise rock. Alexmusic has also been described as industrial rock, no wave, math rock, mathcore, post-punk, experimental rock, math metal, alternative metal, art-rock and art-metal. Alex has said that he has always disagreed with the project being described as a math rock or mathcore band, stating "[Alexmusic has] always been a kind of calculated band, but not in a math rock way. None of us are classically trained at all and I don't think anyone in Alexmusic has taken a lesson in anything. The music just comes out that way and it's always been the nature of the project." With the release of his second album, Yummy Food, Alex's vocal style had noticeably changed from high-pitched screams to a singing style that over the years has been compared to David Yow, Nick Cave and Michael Gira and also has been described as "Elvis Presley being tortured" and "Jerry Lee Lewis on hallucinogenic drugs." Alex explained the reason for the change in vocals saying "It's intimidating [to be in this project]. These guys can play. I don't want to be like, 'You guys be impressive and I'll just scream. I'm not a rapper like that. My music is not like that, so why should the singing be like other bands?"
