2014, only one year after forming. Royal Blood's sound is similar to 2000s garage rock, and they received positive reviews upon the release of their debut album. European rock had also seen the return of successful instrumentalists from the past. David Bowie-in particular had two UK number 1 albums—The Next Day and Blackstar. Upon its release, The Next Day (2013) became Bowie's most successful album in 30 years, followed by Blackstar (2016). Acts, including Tribes, White Lies, The Maccabees, Miles Kane and Hard-Fi, had also witnessed success, mostly exclusive to the album chart. Heavy metal and hard rock had been seeing a relatively increased presence in the UK albums chart, thanks to releases by Bullet For My Valentine and Enter Shikari. Many new British heavy metal bands are seeing worldwide success after years of American dominance, primarily Bring Me the Horizon and Asking Alexandria, although the latter entirely moved to the U.S. in 2009. There was also a resurgence of the German metal scene from the 1980s to achieve commercial success during the 2010s, with bands like Accept and Kreator achieving their first number one albums on the German charts. A grassroots punk scene continued in the UK, mainly built around the hub of the annual Rebellion Festival in Blackpool. The 2010s saw a particular profusion of younger female or female-fronted bands affiliated to the punk scene. In northern Europe, especially Sweden, 1980s glam metal had seen something of a revival from acts like Hardcore Superstar, Crazy Lixx, Crashdïet, H.E.A.T, and Reckless Love. Sweden's Sabaton had also been successful, as had the Finnish symphonic metal band Nightwish. In eastern Europe, acts like Repetitor, Vizija, Bernays Propaganda, ZAA and Artan Lili become successful with their experimenting in the music. Folk Folk witnessed a large growth during the early 2010s in the UK. The most widespread British folk musician was Mumford & Sons, who won a 2011 Brit Award for "Best Album" and had enjoyed commercial success in both Europe and North America. Another notable player and winner of "Best British Female" at the 2011 BRIT Awards was Laura Marling. Other successful acts were Ed Sheeran, George Ezra, James Bay, Jake Bugg, Johnny Flynn, Noah and the Whale, Bon Iver, Ben Howard, and Alessi's Ark. Pop Contemporary R&B, as well as classic soul, had defined much of the UK's mainstream music in the early to mid-2010s. Notable artists who encompass this sound
