Query: Shades Apart's 'Eyewitness' - A Power Pop Gem

When compared to previous Shades Apart releases, 'Eyewitness' is restrained in tempo and crisply produced. It is also clearly the band's most mature and diverse recording to date. While "Valentine" is catchy and heartfelt, tunes like "Edge of the Century", "Sputnik (Watching Over You)" and "Second Chances" pack more of a power-pop punch. And you can't help but feeling good after hearing out the album's blazing closer, "Speed of Light". After many years of hard work and little acclaim to show for it, I am pleased to see that Shades Apart still aspires to make great original rock and roll music. If you enjoy edgy pop rock with a little jolt, 'Eyewitness' is well worth your while.
