“A Tab In The Ocean”: a 16 minute opus from the band Nektar. This is in many ways as much a rock opera as The Who’s “Tommy”. Riffs and phrases repeat throughout the extended length song. Monster riffs, guitars, a majestic organ line, and impassioned singing make this a truly memorable track. Did Rush get inspiration from this number and apply it toward their own epic composition, “2112”? You betcha.
