American heavy metal band Metallica is letting its reign loose by toning down one of its ferocious hits Enter Sandman into a joyous number.
The band turned the 1991 hit into a ramshackle jam, performing the track with toy instruments alongside Jimmy Fallon and The Roots on The Tonight Show Starring Jimmy Fallon, reports rolingstone.com.
Lead Vocalist James Hetfield could not help grinning all the way as he belted the song over the joyous ruckus.
Meanwhile, lead guitarist Kirk Hammett wailed away on a melodica and bandmate Lars Ulrich pounded on a colourful microscopic drum and smashed together a pair of tiny cymbals.
Members of Philadelphia-based hip hop group The Roots huddled up for the performance beside Fallon and the band in the small room with tiny instruments.
