Every week, Amazon.com is letting us select one album from its MP3 store to go on super sale (up to 75% off normal prices). Hopefully you'll be able to add these must-own LPs to your library without breaking your budget. Today's deal: Boards Of Canada's Music Has The Right To Children.Scottish brothers Michael and Marcus Sandison have been releasing cut-and-paste collages since the late '80s, but 1998's Music Has The Right To Children (Warp) was their first proper studio LP. Ten years later, it remains one of the greatest IDM efforts of the modern era and an inspiration for ambitious electronica artists and Radiohead alike. The elusive duo's name is inspired by documentaries from the National Film Board of Canada, and even if you're not aware of that oeuvre, the sounds collected on Music will be familiar to anyone who's watched a '70s educational filmstrip in elementary school. Warped, warm synths and electric pianos mingle with found sounds and echoing kids' voices, forging a trippy tribute to childhood wonder. Off-kilter beats and samples appear incongruously with the analog sounds, a la labelmate Aphex Twin, ensuring that we're never in Muzak territory. Every track is transportative and psychedelic, and while BoC have remained vital throughout their career, we most frequently return to the ambient soundscapes of their debut. This week you can pick it up at Amazon MP3 for g.99 down from the regular price of .99.Help us make great albums available at low prices by suggesting future Friendly Deal selections in the comments.
