The Quadrature by Daniel Wyckoff is an acoustic instrumental progressive haven. It's not everyday that we cover instrumentals here in Frostclick, so here's one to feast your ears on. Daniel Wyckoff is a guitar aficionado that has just released his second record of nothing but sweet acoustic guitar goodness for free. His second album, A Shift, is available as a free download on Jamendo. Before that though, he released The Quadrature which feature a lite-prog and math rock sound. The recording quality isn't perfect but you have to admire this guy's skill and what he can do with his guitar.
