Thanks for the responses. Yes, I hail from Kansas City.
I plan to be there, but my brother is very ill, and I might have to be at his side. His wife is debating what's best to do at this point.
The venue, Kansas City Strings, is a music store, dark red brick with plate glass windows. It is on the west side of Merriam Drive, and it is the second building north of Johnson Drive. Johnson Drive is the first street north of Shawnee Mission Parkway (Hwy 56.) All of this is 1/2 (I think) mile north of where I-35 crosses 56.
there's parking on the street and in the back, but I'm not sure exactly how one gets 'in the back.' The neighborhood is pretty quiet on a Saturday night, and parking doesn't present a challenge.
