Charlie Mosbrook takes the stage in the Cambridge Theater at the House of Blues on Monday the 24th.  It's open mic night, and various artists come spilling as the night goes on.  Their performances range from folk, (like our folk singer and songwriter Charlie Mosbrook) rock, freestyle, or acappela, it all happens here every Monday night.  Whether you're an artist looking for a place to perform, or just someone who's looking for a comfortable, cozy, and hip setting, send yourself to the Cambridge Theater.  You're bound to be inspired in one way or another.
