John nodded at the question, though he couldn't help the slight grimace at the thought of the taste. "Yeah. It works decently as a substitute. It originated in the world my sire came from. I suppose the City just copied it, or brought some in, or something."
He let the matter drop then, if Eric had questions John was sure he'd ask. He nodded at the suggestion and turned, pocketing the keys as he walked into the sound booth and then pulled on the guitar strap. He admired it for a moment, checking the amp and then strumming experimentally. The instrument responded with a clear sound as he plucked at the strings, and he settled on the stool inside with a bright grin as he started to play.
