Rockland-based electronic/ambient duo Algorithm will returns to Åarhus Gallery, 50 Main St., Saturday, Oct. 27 at 7 p.m. The group is comprised of Mike Whitehead on trumpet and flugelhorn; and Tom Luther on keyboards.

The basic form of Algorithm is supplemented by substantial use of electronic instruments, both live and sequenced. Both musicians are experienced jazz performers and use their improvising skills in the context of modern electronica and ambient music.

"We're truly an amalgam of several different approaches," said Luther.

The idea of playing along with recorded material goes back to the early electronic music of the French musique concrete, while Algorithm’s sound is really more related to the work of Brian Eno and Jon Hassell in the 1970s, he added.

“In one sense it’s really an extension of our jazz performance, but in another it’s a complete departure," Luther said.

Both musicians compose for the group and create the electronic textures that serve as the musical landscapes which they traverse during their performances. Algorithm combines the fixed electronic backgrounds with live mixing and improvisation to make each performance unique and infinitely variable.

"It can get a little dicey managing the live performance with the manipulation of the technology, but it really adds a potent element to our performances,” said Luther.

Suggested donation is $10. Light refreshments will be served. For more information, call 338-0001.
