The world was their stage, and even after they left it, their music and legacies live on. Today, we commemorate three men who have shaped our musical world - Michael Jackson, Craig Strickland, and Pierre Boulez.

Spike Lee's new documentary, "Michael Jackson's Journey from Motown to Off the Wall", will premiere at the Sundance Film Festival and air in February during Black History Month.

In a recently released clip, a young Michael Jackson is seen talking to a 20/20 reporter in 1980 about going solo. He says he doesn't feel guilty leaving his brothers to strike out on his own.

Sony Music's Legacy Recordings will also re-release Jackson's revolutionary 1979 album, "Off the Wall."

The 29-year-old is featured in the music video for his band's fan-favorite song, "Torn."

And Pierre Boulez, former Principal Conductor of the New York Philharmonic, has died at the age of 90.

Born in Montbrison, France, in 1925, Boulez initially studied mathematics as a youth before switching to music. Among his most famous compositions is 'Le Marteau Sans Maitre' or 'The Hammer Without A Master', a setting of surrealist poetry by Rene Char for six instruments and alto voice.

He turned more and more from composition to conducting, succeeding Leonard Bernstein to lead the New York Philharmonic, then went on to conduct the BBC Symphony Orchestra during the 1970s. His recordings won more than 25 Grammys.
