New York's medieval fantasy doom metal warriors Castle Rat bring their immersive theatrical experience to Cornerstone on Saturday, September 20. Led by "The Rat Queen" Riley Pinkerton, this mystical quartet weaves crushing Sabbath-influenced riffs with elaborate fantasy storytelling, complete with costumed characters and choreographed battle scenes that transport audiences into their mythical realm. Fresh off the success of their debut album "Into The Realm" and with their sophomore release "The Bestiary" arriving this fall, Castle Rat delivers spellbinding live performances that combine heavy doom metal with swords, sorcery, and pure theatrical magic at Cornerstone Berkeley.
