Matt Krempasky 


Matt began his drum corps career way back in 1975 with the Wayne (NJ) Monarchs.

While at Gettysburg (PA) College, Matt marched with the Reading Buccaneers, winning two

DCA World Championships. In 1982, the Bucs Brass Caption head Tony Yaklich asked him to

be his assistant at Reading and also at his new gig with the Crossmen. Matt starting writing

the brass arrangements for the Buccaneers in 1983, and has been writing for marching arts

ensembles steadily since then. Matt rejoined the Crossmen as the Brass Arranger from 1987

through 1994, helping to create a new signature sound and personality to lead the corps back

to being a consistent DCI finalist. The five year stretch from 1990’s “New York Voices” show

through the “Songs for Planet Earth” trilogy remains one of the most exciting and successful

runs in the corps history. (...and he just wanted to note that he is still in awe of the effort given

by the ’89 corps to somehow get back to being in finals....) Matt wrote and transcribed the

brass arrangements for the Play in the Park performance in 2018.

Matt has been a member of Mensa since 1990. He was awarded the New Jersey “Master

Music Teacher” by the NJMEA in 1997. He was elected to the Reading Buccaneers Hall of

Fame in 2006, the Pennsylvania Drum and Bugle Corps Hall of Fame in 2011, and the

Crossmen Hall of Fame in 2012.

Matt has recently retired from a 40 year career as a high school band director (Roxbury ’82-‘85,

Columbia ’85-‘00, Somerville ’00-‘22) and is excited to have the time to actually practice his

trumpet for the first time in a long, long time. Let’s go get better!
