Steven Tyler, decked out in his classic floppy hat, aviators, and scarves on mic stand all in tow kicked off Aerosmith's set with "Love Is An Elevator" before immediately launching into a series of classic hits. 

He got down for "Oh Yeah" shouting "Vegas, can you feel it?!" all the while constantly pointing his mic at the crowd to sing along and making his way back and forth between super star guitarist Joe Perry and bassist Tom Hamilton. Steven Tyler 

"I want to make you jump," exclaims Steven Tyler. He then introduces "Mr. Sweet Emotion - Tom Hamilton," who came out donning a sparking gold bass with two iPod touches glued on to them, which by the way, were recording the entire crowd. Pretty awesome. 

After "Sweet Emotion," Steven spent some time serenedaing the audience with "Dream On" beforing kicking it up a notch with their final song. Aerosmith closed their set with "Walk This Way" and left with "Good night iHeartRadio, good night Vegas, good night beautiful people, good night!" and a good night from you guys too!
