It's been announced that BUMP OF CHICKEN will be postponing the release of their live Blu-ray 'BUMP OF CHICKEN LIVE 2022 Silver Jubilee at Makuhari Messe' and CD single "SOUVENIR." 

'BUMP OF CHICKEN LIVE 2022 Silver Jubilee at Makuhari Messe' features footage from the band's 25th anniversary live, which was held in July at Makuhari Messe. Meanwhile, "SOUVENIR," which is the opening theme for TV anime 'SPY×FAMILY,' will include a total of three tracks. While both were originally scheduled to be released on December 21, due to some circumstances with the production the new release date has been set to April 5.
