10 Most Underrated Progressive Rock Albums Of All Time

Blink and you'll miss it, this cosmic gem from the Canterbury scene of the early '70s is a work of compelling, hallucinogenic art. Sadly, for all of their potential, Khan never got out of first gear after this and quickly disbanded.

This hectic space-focused adventure is full of concept album tropes and storytelling without ever fully committing to being one. Instead, the group keep most of the tracks at a more conservative length and jazz them up with bizarre musical concoctions. Look no further than 'Stranded', a moody, slow burning rock romp boasting incredible drum, guitar and organ interludes.

Nick Greenwood's sterling bass playing forms a nice rhythmic backbone throughout this album's heady, curious highs. Frontman Steve Hillage carries the lyrics with clean, crisp vocals, allowing the often ridiculous themes and stories at play to resonate clearly with listeners.

While the LP was not a mega-hit upon release in 1972, it did garner enough interest that a sophomore effort seemed like the way to go. Unfortunately, repeated line-up changes lead to the dissolution of the group before it could really get going. The closest fans have ever gotten to a second Khan LP is Steve Hillage's 1975 solo effort 'Fish Rising' which included material once meant for the short-lived outfit's next effort.
