Headliners: font - cursive for classical music concerts (opera, ballet, classical music) bold for headliners (broadway, big time singers/ musicians/ etc.) sharp for contemporary concerts (radio artists) times new roman or similar fonts for informational or articles
An interesting (and pretty appealing, design-wise) look at typography. The information based on operating systems definitely represents the differences in style the OSes like to go for - Windows being traditional, Apple a bit trendier and Linux being all functionality. I'm typically not a fan of white text on black background, but in this case I think it's functional enough. The smaller text is tough to read - I'd vote for larger fonts across the board on this design.
