Cellist Maya Beiser reveals her instrument’s vast capabilities in “Time Loops,” the album of mystical works written for her by composer and pianist Michael Harrison. NPR placed it among the top 10 recordings of 2012. This week, Beiser and Harrison share its centerpiece, “Just Ancient Loops,” in a concert at the Atlas Performing Arts Center. Selections by Arvo Part and Evan Ziporyn are also on the program.

The title is a study in itself. According to Harrison, “Just” refers to the tuning system incorporating mathematical harmonies from ancient Greece. “Ancient” refers to the modes and harmonies, while “Loops” indicates the loops of melody and rhythm that create an odyssey for an orchestra of cellos.
