David Morrissey is a California native from Los Angeles. In 2008, he won the International Audition for the Calgary Philharmonic Orchestra. He began playing the cello at the age of eight, and while in high school, started taking lessons with Ronald Leonard at the University of Southern California while enrolled in two high schools, Long Beach Polytechnic and The Orange County High School for the Arts.   He received his bachelor’s degree from Indiana University, Bloomington, where he studied with Tsuyoshi Tsutsumi and Janos Starker, and his master’s degree in cello from Manhattan School of Music as a student of former Associate Principal Cellist of the NY Philharmonic, Alan Stepansky.


Morrissey continued his orchestral studies in Miami Beach, Florida, with the New World Symphony, an Orchestral Academy, under the musical direction of Michael Tilson Thomas. In 2001, the Leipziger Volkszeitung called him “a cellist with a bright future,” and his performance of the David Ott Double Cello Concerto with the Evansville Philharmonic in 2003 was praised by the Evansville Courier Press as “exemplifying the purest sound and musical taste.” His performances have taken him all over the U.S., as well as Rome, Montepulciano, Leipzig, Berlin, and Tokyo, just to name a few, and he is one of the founding members of the Young Janacek String Quartet. In 2017 he started instructing young cellists at the Calgary Philharmonic's Phil Kids after school program.  He also teaches his own students in his cello studio, and is a cello instructor at the Mount Royal Music Academy. 


In his spare time Morrissey enjoys swimming and yoga-ing and he is an avid outdoor enthusiast with a passion for exploration. He spends his summers performing with the Colorado Music Festival in Boulder, Colorado, and climbing 14ers (mountains that exceed the 14,000 ft mark)

Kat Hammer plays many different types of guitars – focusing on
renaissance and baroque period instruments. Kat has studied in Canada,
Germany, and England, and has a MA in Music Theory and Analysis. In
2017 she was the soloist in Blue Arch Strings' performance of
Vivaldi's lute concerto. In addition to performing and teaching, Kat
recently edited a 17th century manuscript of the music of Antonio de
Santa Cruz. She is a member of the YYC Guitar Quartet, performs on
lute, theorbo, and baroque guitars in various solo and chamber music
settings, and teaches guitar and mandolin.

Justin Luchinski began an active career in early music performance in Montréal while completing his Bachelor of Music and Master of Music degrees, with honours, at the Schulich School of Music, McGill University. Before moving back to his hometown of Calgary, AB in the summer of 2020, Justin was a regular rehearsal keyboardist with Opera McGill’s baroque opera productions for over half a decade, and had regular season concerts, performances at the Montréal Baroque Festival, recording projects, and nation-wide touring with Les Méandres, the ensemble of which he is a co-founder. The “sensitivity and nuance” of Justin’s playing has been shaped largely under the tutelage of Hank Knox, but has also been heavily influenced through masterclasses with Charlotte Nediger of Tafelmusik, Marie van Rhijn at L’Académie des Musiciens de Saint-Juilien, Mark Edwards, and others. Since returning to Calgary and acquiring a replica of a 1681 Vaudry harpsichord, Justin has worked with Calgary’s highly acclaimed Luminous Voices, collaborated with various members of the Calgary Philharmonic Orchestra, co-founded a Calgary-based early music ensemble called Galatea, and started an early chamber music concert series called Chamber Muse, generously funded by the Alberta Foundation for the Arts.
