“I don’t know where to stand,” Portland composer, violist and violinist Kenji Bunch confessed to the crowd crammed into Blue Sky Gallery last June. There was after all no stage, and the audience sat in folding chairs arrayed around the downtown Portland art and photography space. Bunch finally decided to start his set of original music with pianist Monica Ohuchi by not standing at all, instead walking around the pianos as he played.

Changing the usual “rules” of classical performance is part of what made Stephanie Ho and Saar Ahuvia’s Makrokosmos Project so successful last year, and why the New York-based duo pianists are bringing it back next week. For one thing, there’s no prescribed duration to the musical “happening” featuring work by living American composers and leading local performers; audience members are welcome to come and go, catching as few or as many of the 40 minute sets as they like.

Moreover, the event, whose second annual performance occurs this month in Portland and Eugene, pretty much obliterates the distinction between the performers’ stage and the audience’s space.

The project strives for “a performance atmosphere that breaks the barriers of traditional concert halls by putting the audience in an intimate space, close to the performers and the music performed,” according to Ahuvia. In a genre that’s too often distanced itself from its audience, it may seem a little crazy; no wonder this year’s theme is American Berserk.

The Makrokosmos Project, which OAW called “one of 2015’s peak Oregon musical moments,” again takes listeners to the acoustic edge at Blue Sky on Thursday, June 23 and then travels up river to Eugene for a festive evening at Oveissi & Co. on the 26th.

Like last year, the program begins at 5 pm with a wine social and the first of a series of short sets each about 40 minutes long.

“This is something that we have been experiencing more and more in our own performing as classical music tries to reinvent itself in public spaces, clubs and other non-traditional venues,” Ahuvia suggests. “We hope to attract a diverse audience, some who are new to contemporary music, by giving them an option to commit to as much or as little music as they desire. A 40-minute set is something most people can handle and having some delicious food and wine helps to spark the conversation afterwards! And having tickets from $10-20 also makes it affordable.”

This year’s featured work, a 40th anniversary performance of Frederic Rzewski’s The People United Will Never be Defeated, includes 36 variations based on the song “¡El pueblo unido jamás será vencido!” by Chilean composer Sergio Ortega with text by the popular vocal group Quilapayún. The composition has been divided among a team of six pianists, which is not typically done, but seems to work well for this festival, according to pianist Alexander Schwarzkopf. Despite the apparent connection between Rzewski’s famous radical composition and this year’s overheated political rhetoric, “no strong political statement was planned beyond the poignancy of ’uniting the pianists,’” Ahuvia explains. “That being said, we love the spirit of contemporary music being political and relevant to our time.”

John Adams’s six-minute American Berserk!, a title suggested by a phrase in Philip Roth’s novelAmerican Pastoral, resonates with earlier American piano music of Charles Ives and Conlon Nancarrow, the composer notes. “This is a piece that we have always liked,” Ahuvia recalled, “and were happy to hear that Lydia Chung had it in her repertoire. Lydia, who we know from Baltimore and our Peabody days, had just relocated to Portland and when asking her about possible repertoire for this summer she mentioned American Berserk. We had an ‘Ah-ha!’ moment, and this year’s festival theme fell into place.”

“We’ve constructed the festival with music that is super edgy, infused with virtuosity, urbanity and jazz,” Ahuvia says. “Nikolai Kapustin, Portland-based Ryan Anthony Francis and especially John Zorn’s Carny all have elements of ‘berserkness.’ There are plenty of ’berserk’ elements in the Rzewski as well.”

DUO Stephanie & Saar will open the festival with music by contemporary American composers influenced by Eastern philosophies and sounds. “Philip Glass brings both drama and meditations toFour Movements for Two Pianos,” Ahuvia notes about the minimalist pioneer whose music owes much to his 1960s work with Ravi Shankar and study of Indian music’s rhythmic structures. “Gerald Levinson’s new piece Ragamalika: Ringing Changes uses actual Indian and invented ragas infused with rigorous contemporary compositional techniques,” Ahuvia explains.

In addition to DUO Stephanie and Saar, performers include Oregon musicians Angela Niederloh (a prominent opera singer and Portland State University professor who was a classmate of Ho’s at Portland’s Wilson High School), Lydia Chung, Julia Hwakyu Lee, former Florestan Trio pianist and Portland Piano International founder and director Harold Gray, Third Angle New Music’s Susan Smith, Reed College professor Deborah Cleaver, FearNoMusic’s Jeff Payne, and Eugene pianist Alexander Schwarzkopf. The Portland second set features mezzo-soprano Niederloh and Stephanie Ho in three early songs by George Crumb and selections from Jake Heggie’s Winter Roses. “The music provides a chilling, lyrical respite from the otherwise high octane music presented throughout the evening,” Ahuvia says.

Niederloh and Payne can’t make the Eugene show, so Alexander Schwarzkopf will play his own new composition, Perspectives (2016) instead of the Zorn piece Payne plays in Portland, and Stephanie & Saar replace Niederloh’s set with their own performance of music by Pulitzer Prize winning American composers from two generations, George Crumb (whose music they hope to program every year in the festival named after one of his major compositions) and David Lang.

“Our message to the audience,” Ahuvia says, “is to come open-minded, have a glass of wine on us, and immerse themselves in new sounds in new settings.”
