Aerosmith plays free outdoor concert in Boston

ALLSTON, Mass. (WHDH) -- Aerosmith performed a free concert in front of their old apartment building in Allston Monday.

The Boston rockers are promoting their new album by going back to where it all started -- and the boys even boarded duck boats to get there.

Thousands of fans lined the streets of 1325 Commonwealth Avenue to welcome Aerosmith back to where they started.

Steven Tyler, Joe Perry and the rest of the band arrived in Allston on what else but a duck boat that left from TD Garden.

Then, introduced by Tom Brady and Patriots cheerleaders, they took the stage.

And, of course, their live location is where they started all those years ago and where they penned their very first song.

The band's hour-long concert showcased classics like "Walk This Way" and "Sweet Emotion" as well as a song from their new album which comes out Tuesday.

Fans stretched for blocks while others had a better position from windows right above the band.

“I'm just an avid Aerosmith fan and had to take a day off work to see the bad boys of Boston,” said Michelle, a fan.

The concert, which kicked off around 12:30 on Monday, was even just cause for playing hooky at work.

“I find it a historic event. Right you know? Once in a lifetime, the guys are going to come back here and play, so figured it was worth it,” said Javier, a fan.

Aerosmith closed out with some confetti and a grand finale.
