“I like being in the situation where I don’t know if something is going to work,” said Amir ElSaffar with a sheepish smile. “It is a special moment for me. And it is part of my diabolical side that I put others through this process.”

ElSaffar will have another “special moment” Saturday night at the Walker Art Center. He will put 16 other top-notch musicians from around the globe — his Rivers of Sound Large Ensemble — through a tricky, difficult interplay involving brass, woodwinds, strings, keyboards and a wide range of percussion.

Rivers of Sound blends contemporary American jazz with the centuries-old music known as maqam, an endangered style once predominant throughout the Middle East and North Africa (its influence extended as far as southern Italy and parts of China). The fusion of these two distinct styles was essentially invented by ElSaffar, a 39-year old Chicago native with an Iraqi father and American mother.

The Walker performance won’t be as daunting as Rivers of Sound’s debut at Lincoln Center in New York in April 2015, where the band performed an 80-minute suite called “Not Two.” Nor will it be as intense as recording the suite in a marathon 14-hour session the very next day.

But the number of times the group has been onstage remains in the single digits, owing to the cost and scheduling logistics of bringing together so many in-demand musicians from throughout the Middle East, Africa, Europe and the United States. (Ironically, the only original member who won’t be present in Minneapolis is Golden Valley native Craig Taborn, replaced on piano by Cuban-born Aruan Ortiz.)
