Metal has a small but not insignificant presence in Singapore's music scene. Many metal bands such as Iron Maiden, Exodus, Morbid Angel, Slayer, Dream Theater and Helloween made Singapore a stop in their tour, at venues such as Fort Canning Park and Singapore Indoor Stadium. Small to medium scale gigs are held almost weekly at locations such as BlackHole212 or The Substation. Most recently, on 15 February 2011, Iron Maiden played to a crowd of 12,000 at the Singapore Indoor Stadium.
