Pretty sure that's the episode Im thinking of. They get into how aforementioned bands were trying tap into various frequencies to illicit extra dimensional (demonic) responses and using various frequencies to achieve tonal "highs" and what not. Didn't work out as planned when channeling the siren entities obviously.
