The Manitou's 'Let's Build Mecha!' e.p. is now available on iTunes in all countries the service currently caters to, which is pretty much everywhere except for a large chunk of the East. If you're not an iTunes aficionado, you can pick it up from Amazon MP3 in their U.S., UK, French, German, or Japanese stores. Unfortunately that's the limit of Amazon's distribution just now (I can't even buy my own songs from them here in Canada!) But hey-ho, that's the way the baked sugary disc disintegrates.
Providing a link to the iTunes release is more complicated: it's different for every country. The best way to find it is to enter 'Let's Build Mecha' in the search box of your iTunes client, or the iTunes LinkMaker.
While you're waiting, why not listen to the title track?
The rest of my back catalogue will be released via these two stores as and when I can commit the time to preparing them.
