In an August 2010 interview, Dr. Dre stated that an instrumental album titled "The Planets" is in its first stages of production; each song being named after a planet in the Solar System. On September 3, Dr. Dre showed support to longtime protégé Eminem, and appeared on his and Jay-Z's Home & Home Tour, performing hit songs such as "Still D.R.E.", "Nuthin' but a 'G' Thang", and "Crack a Bottle", alongside Eminem and another protégé, 50 Cent. Sporting an "R.I.P. Proof" shirt, Dre was honored by Eminem telling Detroit's Comerica Park to do the same. They did so, by chanting "DEEE-TOX", to which he replied, "I'm coming!" On November 14, 2011, Dre announced that he would be taking a break from music after he finished producing for artists Slim the Mobster and Kendrick Lamar. In this break, he stated that he would "work on bringing his Beats By Dre to a standard as high as Apple" and would also spend time with his family. On January 9, 2012, Dre headlined the final nights of the 2012 Coachella Valley Music and Arts Festival, on the weekends of April 13–15 and April 20–22, 2012.
