I think that the musical significance of the band's reunion tours that took place in 2007 and lasted in different forms until 2011 was to prove that the group still had "it." Guitarist Tom Morello was pointed in suggesting that the musical significance of the tour was reflective of political reality:
Is it a coincidence that in the seven years that Rage Against the Machine has been away that the country has slid into right-wing purgatory? I think not. It occurred to all of us that the times were right to see if we can knock the Bush administration out in one fell swoop, and we hope to do that job well.
The musical significance of the tour was one where the band was able to demonstrate that they had not lost their unique style of songwriting and production. The reunion tour which featured frontman de la Rocha and Morello was also significant because they demonstrated musical depth. Being able to use acoustic guitar in their number for the Coalition of Immokalee Workers reflected this musical flexibility. The tour saw the band play at big ticket venues like Alpine Valley and shows in New York City. Musically, the band's tour was significant because it featured Rage standbys such as "Testify" and "Calm Like a Bomb" as well as adding a new song on different legs of the tour. This demonstrated that the group was active and vibrant from a musical standpoint. The tour was significant because it underscored the group's political motivations. As the post- September 11 grip of the nation stifled much in way of creative talent, the tour was a reminder of how groundbreaking Rage Against the Machine was in their message. The tour was able to convey this sense of political activism through the band's music, making it very significant.
