In October 2010, during the SWU Festival in São Paulo, Brazil, The Mars Volta was actively promoting their fifth studio album, "Octahedron," which was released in June 2009. This period marked a transitional phase for the band, as they began to explore a more concise sound compared to their earlier, more sprawling work. Interestingly, "Octahedron" showcased a shift towards more structured compositions, a notable change from their previous albums, which were typically characterized by extended instrumentals and complex time signatures. Live performances, such as the one at SWU Festival, emphasized their dynamic stage presence while also revealing some imperfections, as noted by fans regarding Cedric Bixler-Zavala's vocal slips. This performance underscored their ongoing evolution as artists, balancing technical prowess with the spontaneity of live music.
