**Reviews:** 0

From the horror cabaret and glam-rock theatrics of his early career to the shadowy, neon-lit world of his current dark synth-pop, Austin-based performer Caleb De Casper has never stopped evolving. A classically trained pianist and vocalist, De Casper commands the stage with a sharpened, unmistakable intensity — trading in the avant-garde gowns and stilettos of the past for a bold, more masculine and unfiltered presence that puts the focus squarely on the music, the message, and the electricity of performance. His 2022 debut LP Femme Boy expanded his sonic world, weaving dancefloor heat, cinematic drama, and queer storytelling into a record that was equal parts brooding and explosive. That same year, the City of Austin proclaimed Caleb De Casper Day, recognizing his cultural impact. He went on to perform yearly at SXSW, Austin City Limits Music Festival, Utopia Fest, Houston’s Art Car Festival, Thin Line Fest,  and multiple Pride celebrations, while continuously advocating for LGBTQIA rights at the Texas State Capitol and beyond. Now, with his forthcoming sophomore album Delirium, De Casper enters a new creative chapter — darker, dirtier, dance-driven, and poised for a breakthrough.
