The second in producer Jonas Tauber's "Zurich Series" for Origin, "Prime Numbers" is a wholly improvised journey through nine original tunes, all based and inspired by prime numbers. Thoughts of an intellectual exercise are soon laid to rest as the recording unfolds in an organic sea of deeply musical explorations. Featuring longtime purveyors of the Northwest free jazz sound - pianist Doug Haning and drummer William Thomas - Zurich-based bassist Jonas Tauber finds great foils for his deep, classically rooted virtuosity.
