While Brazil has no shortage of great surf groups, if you asked me to name the first that comes to mind, it would probably be the Dead Rocks. They've been around for about 10 years now and put out some great albums, my favorites being International Brazillian Surfs and One Million Dollar Surf Band. They're relentless promoters and have made their music easy to obtain across the world. And most importantly, who can forget those sharp outfits. After a brief Spaghetti Western stint on their last LP, they're back to plain ol' surf and doing it well. This has a great mix of mood and tonality, keeping it fresh for a straight-through listen while absolutely pallatable to your average surf fan.
And of course, you can give it a full listen through this bandcamp stream.
