Many eons before "Uno, Dos, Tres, Catorce" perplexed the globe, another number sequence was developed, one more fantastical and meaningful than Bono's counting dyslexia. This ordering of numbers, called the Fibonacci sequence, is by my limited arithmetical ability, a mathematical way of expressing patterns in nature.

Its relationship to the Golden Mean (a mathematical ratio also found in nature and applied to the study of aesthetics) and appearance as plot devices in conspiracy stories like the Da Vinci Code has brought the Fibonacci sequence out of the halls of academia and into the limelight of pop culture. But who knew even trance DJs were budding math enthusiasts?

In 1999, Global Underground released its 13th collection, Global Underground: Ibiza. The two-disc set featured the DJ skills of Sasha, the golden god of the trance genre at the time. "It's the culmination of the late-'90s trance movement at its peak," wrote Jason Birchmeier for All Music. "And as a culmination, this zenith is at times impressive, featuring the era's best producers: Breeder, Quivver, L.S.G., Sander Kleinenberg, and Cass and Slide."

The collection also includes BT's "Fibonacci Sequence" (MP3), which layers vocal loops reciting the sequence ("one, one, two, three, five, eight, 13, 21.") and other numerical maxims like "mathematics is the language of nature" over a cavalcade of propulsive techno riffs. The song is so funky and geometric even Tom Hanks in a mullet could rave to it.

Yes, in the end everything comes back to progressive house.
