I found these guys using this website. I looked for metal shops in Singapore, Malaysia, Thailand, Cambodia, and Laos, but couldn't find any, until I rocked up to Coi Xuong Rock Shop.

It was a welcome relief. They have many t-shirts, metal and otherwise, keychains, Vietnamese metal CDs, and more.

The owner is very talented, with his own website and logos.

The staff were very welcoming, and gave me lots of advice for Hanoi and metal in Vietnam. We even posed for the obligatory metal photo inside the shop.

Definitely check it out.

Went here in Oct 2007. It's a tiny place, down a little alley, hard to find, with sporadic hours. Really more of a guy's living room with two racks of metal T-shirts in it, then a proper record shop. But definitely worth checking out if only for the novelty of how ghetto/underground the place is.
