Metallica played the biggest show Ecuador has ever seen this week when they played to more than 35,000 people at the Bicentennial Park in Quito this week as part of their ongoing Latin American tour.

As at Sonisphere, Metallica are performing "By Request' sets in Latin America where the fans get to vote for the tracks they hear. Although as a treat they are also showcasing one new song. In Colombia and Ecuador that new track is "Lords of the Summer'. You can listen to a garage demo version of it below.
