The Wind Ensemble, directed by Jason Caslor, in the Herberger Institute School of Music, Dance, and Theatre at Arizona State University honors its rich history while reflecting the “state of the art” through dynamic and innovative performances. The Wind Bands at ASU have performed multiple times at national conventions of the College Band Directors National Association (CBDNA), the American Bandmaster’s Association (ABA), the Music Educators’ National Conference (MENC), and the Midwest International Clinic.

An American whose music has been characterized by "propulsive, syncopated rhythms, colorful orchestration, and instrumental virtuosity," (Robert Kirzinger, Boston Symphony) Composer Kevin Day has quickly emerged as one of the leading young voices in the world of music composition today, whose music ranges from powerful introspection to joyous exuberance. Kevin Day is an internationally acclaimed composer, conductor, and pianist, whose music often intersects between the worlds of jazz, minimalism, Latin music, fusion, and contemporary classical idioms. Day serves as the Vice President of the Millennium Composers Initiative, a collective of more than 120 composers from several countries around the world.

A winner of the BMI Student Composer Award, a three-time finalist for the ASCAP Morton Gould Young Composer Award, and considered for the 2022 Pulitzer Prize for his Concerto for Wind Ensemble, Day has composed over 200 works and has had numerous performances throughout the United States, Russia, Austria, Australia, Taiwan, South Africa, and Japan. His works have been programmed by the symphonies of Boston, San Francisco, Detroit, Indianapolis, Houston, and more, as well as several top professional and collegiate wind ensembles. His works have been performed at Carnegie Hall, Rachmaninov Hall (Russia), The Midwest Clinic, and other major venues, and recently he had his Carnegie Hall Conducting Debut at the 2022 New York International Music Festival.

Day has collaborated with the likes of David Childs, Nicki Roman, James Markey, Wendy Richman, Jens Lindemann, Demondrae Thurman, Hiram Diaz, Steven Cohen, Jeremy Lewis, and more on works for their respective instruments, as well as chamber ensembles like One Found Sound, Axiom Brass, Ensemble Dal Niente, The Sheffield Chamber Players, The Puerto Rican Trombone Ensemble, The Zenith Saxophone Quartet, The Tesla Quartet, and the Boston Symphony Orchestra Low Brass Section.

Day is currently Assistant Professor of Composition at Wilfrid Laurier University in Waterloo, Ontario, Canada. He is pursuing his DMA in Composition from the University of Miami Frost School of Music, where he studies with Charles Norman Mason, Dorothy Hindman, and Lansing McCloskey. He holds a MM in Composition from the University of Georgia, and BM in Performance from Texas Christian University (TCU). He is an alumnus of Kappa Kappa Psi National Honorary Band Fraternity and Phi Mu Alpha Sinfonia Fraternity of America.

Born and raised in North Battleford, Saskatchewan, Canada, Jason Caslor is currently an associate professor of music and the director of bands at Arizona State University (ASU). In addition to directing the wind ensemble, he also mentors graduate conducting students and teaches undergraduate and graduate conducting courses. Recent highlights include the first commercial recordings of Kevin Day’s 2022 Pulitzer Prize in Music nominated Concerto for Wind Ensemble and Carter Pann’s Double Concerto “Baroque” with the ASU Wind Ensemble.

From 2015–2019, Caslor was an assistant professor and the associate director of bands and orchestras at ASU. Highlights of that time include founding the now firmly established ASU Philharmonia and being nominated for ASU’s Outstanding Master’s Mentor Award. From 2010-2015, Caslor was an assistant professor of instrumental conducting at Memorial University in St. John’s, Newfoundland, Canada where he conducted the wind ensemble and oversaw the undergraduate and graduate instrumental conducting programs. Prior to that, he spent three seasons as resident conductor with the Thunder Bay Symphony Orchestra (TBSO). During his tenure with the TBSO, he conducted more than 75 concerts (including a CBC Radio national broadcast) and recorded a full-length, internationally distributed CD with Canadian blues artist Rita Chiarelli.

A Conn-Selmer Educational Clinician, Caslor has guest conducted or adjudicated in every province in Canada and throughout the United States. In addition to numerous regional engagements, Caslor has conducted the United States Army Field Band, the National Youth Band of Canada, the South Dakota All-State Band, the South Dakota Intercollegiate Band, and the Alberta Wind Symphony. He also served as a conducting clinician for the inaugural CASMEC Conducting Symposium.

A fiercely proud Canadian currently living amongst cacti, Caslor’s co-founding and leadership over the Canadian Band Association’s (CBA) Howard Cable Memorial Prize in Composition lead to him being the recipient of the CBA’s 2022 International Band Award. The award recognizes those individuals who have embraced the ideals of the CBA and have contributed to the promotion, growth and development of the musical, educational, and cultural values of Canadian bands outside of Canada.

As a researcher, he has presented his work at the Midwest Band and Orchestra Clinic, the WASBE International Conference, the CBDNA National Conference, the IGEB International Conference on Wind Music, the International Society for Music Education World Conference, and the Riksförbundet Unga Musikanter Wind Band Symposium (Sweden). He has also published numerous articles, most prominently in the Canadian Winds journal.

Caslor completed his doctorate in conducting at Arizona State University. Prior to earning a master's in conducting from the University of Manitoba, he earned dual bachelor's in music and education from the University of Saskatchewan, Canada.
