Crystal Knives

Crystal Knives is the stage moniker of Milwaukee-based electronic music producer and songwriter Spencer Mutsch, who found mainstream success in 2018 with the release of "Mannequin," a club hit featuring Casey Cook. Subsequent team-ups with Ivish ("So Numb"), Kayla Diamond ("Beautiful Chaos"), and Lex Allen ("Spooky, Scary Skeletons"), the latter of which cracked the TikTok Top 50 in 2024, helped bring Mutsch further into the EDM mainstream.
