Boston deal in meticulously fabricated hard rock with a technical precision unrivalled by their peers. The brainchild of mechanical engineer Tom Scholz, the sonic perfectionists achieved stardom in the late '70s thanks to colossal, energetic jams like “More Than a Feeling” and “Rock & Roll Band”, which nestle Brad Delp's high-altitude cry in endless layers of guitars that sound like rocket thrusters and laser guns. The outfit also bust a mean power ballad—check out the glorious, soaring “Amanda”, which sounds like a transmission from the cosmos.
