Tim Meeks

First, we meet Tim Meeks, the Baltimore County native who designed the harpejji (pronounced "har-PEH-jee"), a cross between an electric guitar and a piano that has been used by, among others, Coldplay, A.R. Rahman with Florence Welch of Florence and the Machine.

Then, it's uke time, with the Thunder Hill Jug Band/Thrift Shop Tuxedo Orchestra, featuring Jared Denhard, Ed Goldstein and Richard McCready.
