young grime MC's also began to emerge, such as Stormzy, AJ Tracey, Novelist, Jammz, and Lady Leshurr. In 2015, Kanye West invited various grime artists to join him on stage at the Brit Awards. Following criticism of the performance, Stormzy released "Shut Up", using the 2004 instrumental "Functions on the Low" produced by XTC, a member of Ruff Sqwad. The song was a massive hit for Stormzy and helped further popularise grime music. Stormzy's performance of the song during the ring walk to Anthony Joshua's Heavyweight boxing match with Dillian Whyte further pushed the song higher up the charts, eventually peaking at number eight on the UK Singles Chart. In February 2016, Ministry of Sound and DJ Maximum released a grime compilation entitled Grime Time, which topped the UK compilations chart. In May 2016, Skepta's fourth studio album, Konnichiwa, entered the UK Albums Chart at number two. The album was awarded the 2016 Mercury Prize, and was later credited for introducing grime to a new generation of fans. In January 2017, Wiley released his eleventh studio album Godfather, debuting at number 9 in the charts. In February 2017, Stormzy's Gang Signs & Prayer was the first grime album to reach number one on the UK Albums Chart. In June, the British Phonographic Industry reported that grime sales had risen over 100% with physical sales growing over 109%, digital sales 51% and streaming up 138%. This led to the Official Charts saying grime had "smashed" its way into the mainstream. By 2018, grime's momentum had begun to slow down. Grime's rise has been credited for 'opening the door' for competing genres, such as afroswing and UK drill, that had begun to take the limelight. In 2019, Stormzy became the first grime artist to headline Glastonbury Festival. National growth As grime became more popular in the UK throughout the mid-2000s, it spread out of London to other major British cities. Birmingham, Manchester, Nottingham, Leeds, Sheffield, Blackpool, and Bristol now have grime MCs who are currently gaining major exposure in the scene and have featured on Lord of the Mics, an annual DVD released by Boy Better Know's Jammer. The national growth of the grime scene has also been evident with many grime artists playing on the urban music stages of the big summer festivals such as Glastonbury, Reading and Leeds, T in the Park and O2 Wireless Festival in Hyde Park.
