The Soloist, starring Jamie Foxx and Robert Downey, Jr., has been stirring up lots of interest, inspiring orchestras around the country to hold food drives, for example. It's also leading to the creation of some fresh artistic expression. To help kick off the movie's arrival in Baltimore, the Charles Theatre will present a dual event in the lobby at 6 p.m. Friday. The Altra String Quartet, from Catholic University, will make music while the graphic/motion artist Kamil Nawratil, known as 2stimuli, will create something visual on the spot, inspired by the performance. The lobby event is free.
