Steven Tyler was in Lithuania to perform in Vilnius when he wandered up to a couple of street performers and started howling at them. Everyone else will tell you he was singing, but just watch the video.
The performers, who were playing “Crazy” on the violin and accordion, looked a little uneasy when Steven started screeching in their ears. Mainly because it was less harmonious and more tribal war cry. The sound that came out of Steven Tyler’s mouth is the sound you make when you want to make dogs angry.
