As lead singer of Aerosmith Steven Tyler was one of the most iconic, bombastic and charismatic frontmen to ever take the stage. Aerosmith saw major chart and commercial success with hits like "Dream On," "Walk This Way" and "Love in an Elevator" selling more than 150 million albums making them the biggest-selling hard rock back in U.S. history. But despite phenomenal success time and time again Tyler's career nose-dived into a negative spiral with drug and alcohol addiction almost killing him yet every time he fell Tyler came back even bigger and better than before. The story of the man with self-confessed 'lead singer's disease' is told by some of the people who know Tyler best including former band manager Steve Leber and childhood friend and former bandmate Ray Tabano among others.
