You can subscribe to their mailing list, and for most events get on the guest list (early in the week), which in turn will entitle you for free admission before 10 pm.
Some events are free if u get on the list, from their site. But you have to go < 10p i think.
It can depend on the event going on that night. Anywhere from free guest list to $25 to start. It will say on their calendar.
