March 2015, bassist Gordon Moakes tweeted he had parted ways with Bloc Party. Following the departure of their former members, Okereke and Lissack started to work on new songs on their own in late 2014. Bloc Party unveiled their new line-up at two intimate gigs in the Los Angeles area (19 August 2015 at The Glass House in Pomona and 20 August 2015 at The Roxy in Los Angeles). Following these performances, Bloc Party also subheadlined FYF Fest in Los Angeles on 22 August 2015. At these shows, the band confirmed that they've finished recording their next album. The shows marked the live debut for new bassist Justin Harris of the Portland, Oregon, indie rock outfit Menomena, who had previously opened several Bloc Party U.S. tour dates in April 2009; and Louise Bartle, who was accidentally announced a month earlier as Bloc Party's drummer by instrument manufacturer Natal Drums in a since-deleted tweet, leading to fan speculation regarding her membership that was ultimately proved correct.

Later in 2016, the band released the standalone single 'Stunt Queen' to mark their performance at the Hollywood Bowl, which Okereke claimed was a "significant milestone" for the band. It marks some of the first new material that featured Justin and Louise as co-writers. March 2018 saw the band announce a series of shows touring their 'Silent Alarm' album which would be played in full. Due to the success of this short tour, Bloc Party announced further dates in 2019 again playing tracks from the whole of their debut. Alpha Games (2020–present) On 22 January 2020, Okereke announced on his personal social media accounts that Bloc Party had begun writing a new album. On 22 September 2021, Bloc Party posted to their official Twitter account a sneak peek of the tracklist/recording progress of their soon to be released sixth studio album.
