In 2019, Opperman ran a successful Kickstarter campaign for his sixth album Chamber Music from Hell. The album was produced by longtime bass player for Dweezil Zappa, Kurt Morgan.[4] It is a contemporary classical concept album about a posthuman civilization and the music that follows. One of the pieces, "Are We Living in a Computer Simulation?" was inspired by the paper by philosopher Nick Bostrom and was featured in Prog Magazine UK.[5]
In 2020, Opperman collaborated with composer/conductor Eric Roth and the Fifth House Ensemble on a tour and album of chamber music from the videogame Undertale by Toby Fox called Undertale LIVE.[6]
