Recording Functionality on 8gb

Thanks for all of the help everyone. I’ve tried the recorder in my pocket with a 5.1 surround sound system cranked, and it suprisingly made a pretty good recording. However, this concert is an AC/DC concert, so this also adds to the wonder whether or not it will be able to record with quality. But just to clarify, I will be able to record for 2 hours straight as long as i have the battery live and space. It wont stop after like 30 minutes or so right?
