David Gilmour (1978) No Way Out Of Here - LOST 70s GEMS

Vastly superior to the band Unicorn's original which had a rootsy feel, Gilmour instead focuses on the atmosphere of and strips it to its grungy melody with his liquid guitar lines and an organ providing a more weighty backdrop. The best is the wailing harmonica intro mimicking the back and froth/up and down melody that is significantly more emphasised here with Gilmour's downbeat vocal drawl.

The combo of Gilmour's power chords and deliberately restrained rock toughness would make this a grunge sound.
