From the remnants of other great bands are often birthed more great bands. Oftentimes these little side projects go under the radar unless you are a hardcore fan, or the new band itself gains a lot of airplay or word of mouth.

Either way, some of the greatest rock bands of all time have been birthed out of other groups.

10. Crosby, Stills, Nash & Young: Formed by the Byrds' David Crosby, Buffalo Springfield's Steven Stills and Neil Young, and Graham Nash of the Hollies, this band has enjoyed a rather illustrious career with a performance at the original Woodstock in 1969, and a string of hits such as the extremely political "Ohio."

9. The Traveling Wilburys: When you combine the efforts of Tom Petty, Roy Orbison, George Harrison, ELO's Jeff Lynne and session ace Jim Keltner, you get the Traveling Wilbury's. Sadly the original lineup only lasted one album due to Orbison's death due to a heart attack at the age of 52 in 1988. But not only were the Wilburys a supergroup, but each member took on his own new persona: George Harrison as Nelson Wilbury, Jeff Lynne as Otis Wilbury, Tom Petty as Charlie T. Wilbury Jr., Roy Orbison as Lefty Wilbury and Bob Dylan as Lucky Wilbury.

8. Velvet Revolver: Comprising former members of Guns N' Roses (Duff McKagan, Slash), Stone Temple Pilots lead vocalist Scott Weiland, and Wasted Youth's David Kushner; Velvet Revolver was one of the greatest supergroups for headbangers everywhere as long as they lasted. VR is currently on hiatus at this point, and Weiland has since left.
