4. Keanu Reeves
https://www.youtube.com/watch?v=Pou4BlE8ocI In the early 1990s, Keanu Reeves began jamming with friend Rob Mailhouse, and the band eventually known as Dogstar was formed. By the mid-90s, the
presence of Reeves allowed the band to open for Bon Jovi, and they even appeared in a few movies. By 2000, Dogstar had released an EP, two albums, and had even played at the Glastonbury Festival, though by 2002 the band had closed up shop. Reeves did play in another band, Becky, though due to Reeves' film commitments and his own admission that he had no serious musical aspirations, he quit the band after a year. To the actor's credit, though, he has kept himself busy with other artistic pursuits outside of acting, such as writing the picture-book Ode to Happiness and directing the critically-acclaimed martial arts movie Man of Tai Chi, while also presenting the film documentary Side by Side. Even if his musical endeavour was nothing more than generic rock, one can't fault the guy for dabbling in so many media.
