I think that's a great idea and I applaud your initiative. Unfortunately, I'm from Landroval and I don't know any musicians from Riddermark. However, don't rule out the option of starting up your own band for the event. You'll probably want to advertise on your own server forums for musicians. You really don't need any prior experience to jump into the music system. It's surprisingly easy with a little instruction, especially if you have the right tools. If you'd like to take that step and need any help, feel free to contact me. I'm eager to support anyone bringing more music to LOTRO.
