If you need that extra shot of adrenaline that music used to give you, hearken back to the boundary-pushing rock-rap musical alliance that Rage Against the Machine introduced to the genre. In the band's 20th anniversary edition deluxe box set titled "XX," fans get two CDs, two DVDs, one 12-inch vinyl LP, a 40-page booklet and a two-sided poster. The first CD includes the original album that was remastered with three bonus tracks of b-sides from the era. The second CD has the original Rage Against the Machine demo tape, recorded in 1991. The DVDs feature the band's free concert in Finsbury Park in 2010, and clips of Rage's early years as it shot to fame. This is a must for any fan's collection.
