The empty Swimming baths could be used as a music venue it could be then linked with the rest of Market street late nights etc
I like the intention, but having played in bands for well over thirty years, the pool building would need serious modification to works as a music venue, either live or recorded. A huge echoing building has it's place for music (think big echo reverberation which could suit some kind of small acoustic ensemble (e.g., string quartet, acoustic guitar) but for live bands they're a nightmare. You have to treat the building acoustically to stop echoes from distracting the musicians and sounding absolutely terrible for the audience. I remember seeing a lot of bands in what used to be called "GMex" in the late 1980s and early 1990s and they sounded awful.
Let me tell you a story...I remember playing in a big village hall at a beer festival a few years ago and my band was on the stage. Our sound from the PA was going out over the heads of the audience, hitting the back wall and coming straight back at us. Every time we got a snare drum hit, you'd get it back off the wall a few milliseconds later. It's incredibly distracting!
I'd love some kind of live music venue in the town, but I'm not sure the pool building would work without significant modifications.
