Steven Tyler (born Steven Victor Tallarico; March 26, 1948) is an American singer-songwriter, multi-instrumentalist, and former television music competition judge, best known as the frontman 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. He completed drug rehabilitation in 1986 and subsequently maintained sobriety for over 20 years but had a relapse with prescription painkillers in the late 2000s, for which he successfully received treatment in 2009. Ever since Aerosmith launched its comeback in the late 1980s and early 1990s with the albums Permanent Vacation, Pump, and Get a Grip, Tyler has remained a relevant rock icon and has embarked on several solo endeavors including guest appearances on other artists' music, film and TV roles (including as a judge on American Idol), authoring a bestselling book, and solo work (including a Top 40 hit single in 2011). However, he has continued to record music and perform with Aerosmith, after more than 43 years in the band. The band's latest album, Music from Another Dimension!, was released in November 2012.
