Japanese teenage girl pop metal band BABYMETAL joined British epic power metallers DRAGONFORCE on stage Friday night, June 12 at the U.K.'s Download festival. Video footage of their appearance can be seen below.

BABYMETAL's song "Road Of Resistance" (formerly referred to as "The One"), which was debuted during the band's November 8, 2014 concert at the Brixton O2 Academy in London, England, is a collaboration between BABYMETAL's production team and guitarists Herman Li and Sam Totman of DRAGONFORCE, whose guitar playing can be heard in the studio version of the track.

As previously reported, BABYMETAL has signed with RAL/Sony Music Entertainment for the U.S. release of the band's 2014 critically acclaimed self-titled debut album. The CD features two bonus tracks and was made available digitally on May 12, with a physical release to follow on Tuesday, June 16.

"Babymetal" was released via earMUSIC in Germany, Sweden, Finland and Spain on May 29, in the United Kingdom, Belgium, Holland, Poland, Switzerland, Norway and Denmark on June 1, and in Italy on June 2

The European release was made available as the standard edition as well as a deluxe edition that includes a bonus DVD compiling six music videos from BABYMETAL.

Since forming in 2010, BABYMETAL — the young trio of 17-year-old Su-Metal (vocal, dance) and 15-year-olds Yuimetal (scream, dance)and Moametal (scream, dance), backed by a four-piece band packing a heavy metal arsenal — has already achieved two major debut singles — "Ijime, Dame, Zetta!" and "Megistune", both of which ranked in the Top 10 Oricon Chart in Japan. Their first studio album, "Babymetal", also earned the #1 spot on Japan's album chart and Billboard's World Album Chart. The official live music video for their debut album's lead single, "Gimme Chocolate!!", has garnered over 24.5 million views on YouTube.

DRAGONFORCE will release its debut DVD, "In The Line Of Fire", on July 10 via Metal Blade. Shot in high definition during the band's show at 2014’s Loud Park festival at the Saitama Super Arena in Tokyo, Japan, the DVD was filmed using nine camera angles to capture the raw energy of DRAGONFORCE's show and instrumental dexterity for which they are rightly celebrated worldwide.

DRAGONFORCE is in the middle of the "Maximum Overload" world tour, which commenced in September 2014 and is due to conclude in 2016.
