When helmeted Cincinnati Electronic Rock band Black Signal released its excellent latest EP, Parallels, in 2019, they didn’t merely upload it to Spotify and wait for the .003 cents per stream to start rolling in. Giving fans an extra-spicy perk, Parallels — which featured vocals from locals like Eugenius, Von Claire and Jess Lamb — was released not on vinyl or cassette but also “on” hot sauce. At Black Signal shows or at blacksignal.bandcamp.com, fans can purchase hot sauce handmade by the musicians. Each bottle — you can choose between habanero pepper and ghost pepper — includes a code to download the EP’s five fire tracks. Black Signal, blacksignal.bandcamp.com.
