Live shows on air: Playing an instrument on radio.

[Lefinch]

Maybe add a recording studio to the radio station. Have the instruments wired up to a sound booth and recorded onto separate tracks, and a booth with a mixing console where you can edit the tracks to make mix tape that can be played on air.

I certainly like this, though I'd beg alongside some kind of "semi round-persistent" mixtape shelf akin to the chapel bookshelf to let those radio hosts (and the musicians who performed) to have a bit of an expanded repertoire to draw upon.
