August 2010. Okereke released a solo album, The Boxer, in June 2010. Produced by Hudson Mohawke and XXXChange, its release was preceded by the single "Tenderoni". Rumours throughout 2011 suggested Okereke had left the group to focus on solo work, though these were denied by other band members. Four and The Nextwave Sessions (2011–2013) Bloc Party started writing material for a fourth album in 2011, but decided not to play live. In the meantime Okereke finished an EP titled The Hunter. The group stated they intended to release a new album in 2012. In May 2012, Bloc Party announced Four, which was released on 20 August 2012, after being made available to stream in its entirety for over a week preceding release. The album was recorded with Alex Newport, who had previously worked with At The Drive In and The Mars Volta, in New York City. Bloc Party released "Octopus" that July and later released another single entitled "Day Four". The band released "Kettling" on 12 November 2012, followed by "Truth" on 25 February 2013. Four peaked at number three on the UK Albums Chart and at number 36 on the Billboard 200. The band debuted new material during their 2013 North American tour, including "Children of the Future" at Rams Head Live!, "Ratchet" at The Pageant, "Montreal" at the Ogden Theatre and "X-cutioner's Song" at Mr. Smalls Theater in Pittsburgh. Lissack later confirmed the band's plans to release a new EP in "northern hemisphere summer". He told Marc Zanotti of Australian website MusicFeeds that the new material was "not like a continuation of the record we've just made, it's a completely separate thing [...] the next step; the next progression". "French Exit" was given its debut live performance at Crystal Ballroom on 24 May. Some of the new material would feature on The Nextwave Sessions, an EP announced on 25 June and for release on 12 August via Frenchkiss Records. Hiatus and line-up changes (2013–2015) During the summer tour of 2013, drummer Matt Tong left the band. Lissack told a Canadian newspaper, the National Post that the band were planning to take an indefinite hiatus following their appearance at the Latitude Festival on 19 July. In October 2013, Kele assembled a DJ Mix for !K7's Tapes mix series, released under the Bloc Party name. In September 2014, Okereke stated that Bloc Party were working on a fifth album. In
