Progressive metal nerds can mark their calendars for Saturday, February 11, the date of the inaugural Subterranean Dissonance Fest in Philadelphia. Headlined by Liturgy, Horrendous and Imperial Triumphant, the festival promises to be a “masterclass in progressive heavy music.”

Subterranean Dissonance features 10 bands across two alternating stages located in the same building, Underground Arts, which makes it a total manageable day of tech death and weirdo black metal. Check out the full lineup:

I don’t know about you guys, but, personally, I love the idea that Liturgy and Thantifaxath are going to play the same stage as Kaonashi. Tickets for the fest officially go on sale tomorrow but you can use promo code SDF2023 to get access a day early.
