Concordia Laptop Orchestra (CLOrk) is an ensemble of laptop performers, consisting of up to 25 members, based at Concordia University's Music Department in Montreal, Quebec, Canada. Founded and directed by professor Eldad Tsabary, CLOrk specializes in networked and multidisciplinary performances and collaborations, such as with dance and video.

CLOrk's first performance (January 2011) was a telematic collaboration with other laptop ensembles across Canada as part of the University of Calgary Happening Festival. Since that performance, CLOrk has performed telematically on several occasions with other laptop ensembles (such as McMaster's Cybernetic Orchestra) and acoustic ensembles at New York University, University of California, San Diego, Queen's University Belfast, Hamburg Hochschule of Music, University of California, Irvine, and Mustek duo (Edinburgh), among others, at international events such as Birmingham Network Music Festival, ToBeContinued, and Penta Locus.

The laptop orchestra trend began with the Princeton Laptop Orchestra (PLOrk) in 2005 and continued with the emergence of many laptop orchestras and ensembles around the world, each characterized by certain technological traits and artistic approaches. CLOrk is characterized by a non-uniform technological approach, based on the idea of "music first; technology follows," by its network music activities, by its collaboration with acoustic ensembles, and by its use of soundpainting conduction.

The Electro-Acoustic Ensemble is a laptop-based ensemble at Loyola University New Orleans. The ensemble was formed in January 2009 by Professor Paul J. Botelho and is composed of thirteen performers. Custom software instruments are developed for the ensemble primarily using the ChucK and Java programming languages. The ensemble focuses on contemporary and classical electro-acoustic works and performs in a variety of situations with a special focus on guerrilla performance.

Futurist Manifesto was premiered at a guest lecture by philosopher Slavoj Žižek at Loyola University New Orleans on November 17, 2009. The work was based on the manifesto of the Italian Futurists and included live recitation of the manifesto with computer manipulation. This work was also performed at the New Orleans Museum of Art on April 1, 2011 as a part of the museum's Where Y'Art? series.

On December 4, 2009, the ensemble performed a twenty-four-hour meta-performance of Erik Satie's Vexations at Loyola University New Orleans. Notably, one audience member, pianist Michael Bennett, remained for the entire twenty-four-hour performance.

The ensemble performed a concert at McKeown's Books and Difficult Music, New Orleans, LA on March 26, 2011.
