To play music on an instrument, often guitar.
Я же пошел в бар, который расположен на первом этаже отеля. В баре живой музон, на пианино очень профессионально лабал местный лабух.
I went to the bar, which is on the ground floor of the hotel. There was live music at the bar, with a local lounge player playing the piano very professionally.
