Steven Tyler is an American singer, songwriter, and multi-instrumentalist, best known as the frontman and lead singer of the Boston-based rock band Aerosmith, in which he also plays the harmonica, and occasional piano and percussion. He is known as the 'Demon of Screamin' due to his high screams and his wide vocal range. He is also known for his on-stage acrobatics. During his high-energy performances, he usually dresses in bright, colorful outfits with his trademark scarves hanging from his microphone stand. In the 1970s, Tyler rose to prominence as the frontman of Aerosmith, which released such milestone hard rock albums as Toys in the Attic and Rocks. In the late 1970s and early 1980s, Tyler had a heavy drug and alcohol addiction, and the band's popularity waned.
