Reunion and Hotel Valentine: 2011–2017
Cibo Matto announced their reunion on March 18, 2011, in advance of the benefit concert for victims of the 2011 Tōhoku earthquake and tsunami. The concert, which took place on March 27 at Columbia University in New York City, also included Yoko Ono, John Zorn, Sonic Youth, and Mike Patton. Following the success of this show, a second was added, this time featuring the Plastic Ono Band and Patti Smith along with Cibo Matto.
The group appeared at the Hollywood Bowl on June 26, 2011, for another benefit, alongside Yellow Magic Orchestra.
On May 16, 2011, Cibo Matto announced its US reunion tour titled "Yeah, Basically Cibo Matto" with a tour website and promotional video. During the shows, the band reportedly spoke about a new studio album that was to be released in 2012. On July 17, 2012, the band announced it would be opening for Wilco at one of its shows. The band included Yuko Araki on drums during this time.
On June 15, 2013, the band played the Meltdown Festival in London and announced that its new album would be released in 2014. While the performance also featured Yoko Ono on "Know Your Chicken", the group also played new songs titled "MFN", "Check In", and "Tenth Floor Ghost Girl". On December 11, Pitchfork reported that Hotel Valentine would be released on February 14, 2014 (Valentine's Day), and that Cibo Matto had shared its music video for "MFN". Hotel Valentine peaked at number 168 on the Billboard 200.
In 2014, the band signed with Japanese label Commmons. This new relationship resulted in several live dates in Japan including Summer Sonic Festival 2014 and shows at Blue Note Jazz Club Nagoya and Blue Note Jazz Club Tokyo.
In September 2014, Cibo Matto released a teaser video announcing their Fall Flavor Tour and a new music video. Rioux opened for multiple US shows. Nels Cline (of Wilco) also performed with the group on tour. The music video for "Déjà Vu" was released on September 18, 2014 in collaboration with New York City-based director Jean Claude Billmaier and creative house Marabigo. Pitchfork identified the video as "a colorful, datamosh-y new video", and Spin as a "stylish bubblegum pop-meets-digital-disaster (intentional)".
Cibo Matto completed two small tours in 2015; an "Avocado Tour" of Japan and a "Banana Split Tour" across the eastern US and Canada. On December 11, 2017, Cibo Matto announced their breakup, explaining that this was a "necessary and positive change".
