Alternative rock veterans Good Charlotte announced Thursday they are going on an indefinite hiatus after fifteen years and five studio albums spawning three Top 40 hits.  "We're stepping away from the grind of making records and touring for a minute," guitarist Benji Madden revealed in an interview with Rolling Stone.  But before they step aside for awhile, the band has a new mixtape titled "Before the Fame: The Madden Brothers," which is set to arrive in stores on October 1st.  The album will feature collaborations with a number of up-and-coming hip-hop artists like Machine Gun Kelly and Rockie Fresh.
