Johannes Moser and Enrico Chapela’s ‘Magnetar’ is a big draw for Cabrillo Festival goers
When it came time for Mexican composer Enrico Chapela to put together a concerto featuring the electric cello, he drew his inspiration from the source of that instrument’s power: electromagnetic energy. Specifically, he based the music on data from flares produced by three different magnetars, an unusual type of pulsar with the largest magnetic field in existence. After compiling a chart of notes that described the shape of each magnetar’s light, he put his guitar in the traditional C-G-D-A tuning of a cello and jammed some ideas that made use of these materials. The resultant concerto, “Magnetar,” can be heard at the Santa Cruz Civic Auditorium on Saturday, Aug. 10 as part of the 2013 Cabrillo Festival of Contemporary Music.
In imitation of the cosmic noise that precedes and follows the pulsar’s blast, “Magnetar”’s first movement begins and ends with the sounds of orchestra members rubbing their hands together and stomping their feet. “The blast itself is a huge, sudden explosion that gradually decreases its magnitude, so it looked to me like an audio event when I saw this graph on paper,” Chapela explains. “For the first movement, I thought it was a better idea to put this audio event backward: to start with a crescendo toward a big explosion at the end of the first movement. So the first movement is basically one of the explosions that I had, but read from the end to the beginning.”
Connecting the concerto’s first and second movements is a solo cadenza in which the electric cello’s signal is processed through such effects as multi-tap delay and ring modulation. “The idea here is [to convey the period] when the magnetars are not exploding—when they are ‘chilling out,’ let’s say,” the composer notes. This passage leads into the slower second movement, which is illustrative of magnetars in their normal, cooler state.
Lest the audience get too comfortable, “Magnetar”’s final movement begins with an explosion. Attesting to Chapela’s history as a rock guitarist is a monstrous riff that the composer simply calls “brutal.”
Johannes Moser, the renowned cellist featured in Saturday’s performance, says his involvement with this piece has made him more familiar with some of the heavy metal music that influenced the concerto’s third movement. “Enrico has introduced me to a lot of bands that I maybe was aware of, but didn’t necessarily listen to much, like Sepultura, Apocalyptica, Metallica—all these bands that you might have heard once or twice, but once somebody introduces you to the subtleties of it, it’s a whole new listening experience,” he offers. “I was mesmerized by the virtuosity that some of these bands have: all the changes of time; how extremely locked in with each other the musicians are.”
The German-Canadian Moser, who recently moved to New York from his native Munich, flew to Chapela’s home in Mexico City in 2011 to be a part of “Magnetar”’s creation. “That’s why this piece is so dear to me,” he states. “I could witness the process of how it was born, rather than just receiving an email with a PDF: ‘Here you are. Good luck.’ To see how Enrico is living, what his rhythm in the day is, to meet some of his friends and the people he is working with in Mexico—that gave me a whole insight into how he understands sound, rhythm and all these kinds of things.”
Also featured on Saturday are Andrew Norman’s “Unstuck” and the U.S. premiere of Philip Glass’ “Symphony No. 10.” An outdoor dessert reception follows the concert, helping audience and orchestra members sweeten their palates after enjoying a generous helping of unusual musical ideas.
This Cabrillo Festival of Contemporary Music concert begins at 8 p.m. Saturday, Aug. 10 at the Santa Cruz Civic Auditorium, 307 Church St., Santa Cruz. Tickets are $32-$52. For tickets and more information, visit cabrillomusic.org or call 420-5260.
