Promoting Born This Way in Australia, Lady Gaga performed a once-in-a-lifetime concert live at Sydney's historic town hall Wednesday.

The town hall, renamed “Sydney Monster Hall” for the event, held an intimate concert exclusively for fans who won a national radio contest.

The official sound and video recording will be released July 29, but one fan lucky enough to sit in the front freaking row has some highlights.

The clip montage below gives you some idea of what it looked and felt like inside the venue, as well as some of the outrageous Gaga getups.

Must have been a pretty awesome concert ...
