Torrid can mean "emotionally charged and passionate," like a torrid romance in a soap opera. But if you’re listening to a torrid band, you’re simply hearing musicians that have a lot of energy.
Torrid is an adjective that can literally describe something extremely hot — like a torrid afternoon in the desert. It also describes something that's very energetic, or something that has an extreme emotional charge — which is why people often apply torrid to intense romantic relationships. Torrid comes from the Latin word torrere, meaning “parch or scorch.”
