Ditto on being British and a fan of bagpipes :)
At the moment we have, I think:
- aguy777 rolling around ideas
- Lord Psynister as a Kenku from the College of Creation, with his mimicry talent
- MadAlpaca as a Lizardfolk on percussion or bagpipes
- Mandacaru as an ex-fighter (class or background) on drums
- thattripletguy on drums or bass
- me as a Dwarf from the College of Eloquence, on longhorn, lute or harmonica
Historically, both percussion ensembles and drum circles are "a thing" and happy to shift one or two of my instrument choices around to fit... or to be the counterpoint sound
For my concept, I'm leaning towards the Feylost background and making him an atypical dwarf
