Legendary Boston rockers Aerosmith released their first video in eight years Tuesday, the first taste of its first new album in eight years, which will be released in November.  Check out the video, for the single "Legendary Child," below.  Aerosmith has traditionally began work on new albums with unfinished work from previous albums, and its new set, "Music from Another Dimension," is no exception.  In fact, "Legendary Child" reportedly dates back a staggering 16 years, originally written during the "Get A Grip" sessions.  The single debuted last month at No. 32 on the Mainstream Rock chart and at No. 2 on the Hard Rock digital songs chart, marking Aerosmith's first appearance on the charts since 2006.
