SIU’s Yellow Moon Gyroid Concert Series features student performers Nov. 7
CARBONDALE, Ill. — The Yellow Moon Gyroid Concert Series at Southern Illinois University Carbondale features six students in the School of Music on Saturday, Nov. 7.
The free, public concert begins at 3 p.m. in Morris Library’s first-floor rotunda.
The Hathor Percussion Quartet — comprised of master’s degree students Will Brady, Lucas Barger, Keaton Jones and Mackenzie Riedy — study under Christopher Butler, assistant professor of percussion. The Indigo Duo — Matthew Charuka and Mika Rabago — study under Eric Mandat, professor of clarinet.
Concert series co-founder Reiko Schoen is excited to introduce all the excellent performers in this program.
“I’ve been listening to each of their impressive performances in the various concerts since they were at SIU,” she said.
Numerous selections
The program includes compositions “Winter Fantasy” by Mandat, “a glimpse into the soul” by Jones and “Rock Duet” No.1 and No. 2 by Charuka. Other works are from Andy Akiho, Johann Sebastian Bach, Eric Sammut and David Bennett Thomas.
“The opening concert of the third season in September was received enthusiastically by the audience along with regular audiences and new listeners,” Schoen said. “I am extremely grateful to the donors’ contributions that helped keep this concert series, also to all the musicians who shared their love of music in past concerts and upcoming concerts.”
There will be a hybrid of printed concert programs for the concert along with a QR code for a print-free way to follow along available at the event.
Series started in fall 2024
The series honors Schoen’s late husband, SIU Carbondale professor Alan Schoen, who discovered the gyroid in 1968 while working for NASA. The rotunda is home to Yellow Moon Gyroid made in Schoen’s honor by algorithmic artist Jesse Louis-Rosenberg.
A gyroid is an infinitely connected periodic minimal surface with no straight lines; a minimal surface has the smallest area possible within a given boundary. Schoen, a physicist, mathematician and computer scientist, taught at SIU Carbondale from 1973 to 1996.
