Calling all Jonas Brothers fans! For the first time ever, MTV will document the band by streaming live video content on the internet in real time.

Jonas Brothers: Live & Mobile will begin on Friday at 4 p.m. ET through Saturday, August 9, from 8 a.m. through 8 p.m. when the band headlines at Madison Square Garden.

Fans who want to get in on the action can go to and watch the live streaming video tomorrow and Saturday.   In addition to the live video streams, MTV will be live-blogging all the goings-on behind the scenes, from 3pm – midnight ET on Friday, and 8am – midnight ET on Saturday.

The Jonas Brothers will also give feedback to a few lucky posters on the site’s interactive wall throughout the day.
