If proggy instrumental moodiness gets your motor running, you'll want to visit Monkey Island with all due speed. Having nothing whatsoever to do with the LucasArts computer game series of the same name, Monkey Island presents six intricate, frequently sinister compositions for guitar, keyboards, drums, horns, turntables and other musical esoterica. Given their lengths -- from six to eleven minutes -- you'd be correct in guessing that none of these tunes progresses in a linear fashion. "The Monarch", for instance, undulates along an arc between math rock and seventies-style fusion-influenced prog-rock, with several stops in the ambient domain. "The Intern", on the other hand, places analog synth at front and center, sounding almost Aphex Twinnish for its early moments, then drops into a tribal rhythm which gradually incorporates a jazz tempo, horns and intermittent new-wave electronics. "The Chairman" adopts a loungy groove that grows steadily more intricate, ending as a complex concatenation of keyboard, guitar and string melodies. If you listen attentively to Monkey Island, you'll gradually begin to figure out its methods, identifying germinating melodies at their earliest stages and observing the causal relationships they create...or, if you prefer, you can simply kick back and enjoy some fascinating instrumentals sans intellectual involvement. Either way, you win.
