Thanks Idlewilde and dilatedmind.
The scene here is small, but dedicated. Will always see the familiar faces at gigs, depending on genre. Iron Maiden, Megadeth (twice), Opeth, Children Of Bodom, Exodus, Arch Enemy, Nile, Chthonic, Slayer, Slipknot, Judas Priest, Lamb Of God (twice), Dragonforce have all played here. Slayer and Slipknot opened the floodgates here. More metal bands are starting to come here and play, which is a good thing.
And the metalheads are all still waiting for Metallica to play here.
I thoroughly enjoyed SW2012. Slipknot, Machine Head, In Flames, Gojira etc. Tiring though. SW2013 was more relaxed for me. Lots of free time in between bands. And SW helped me complete my dream of watching the Big 4. Megadeth in Singapore and the rest in SW13.
