In addition to a New York concert season featuring many of the city's freelancers, Wet Ink performs as a septet consisting of a core group of composer-performers that collaborate in a band-like fashion, writing, improvising, preparing, and touring pieces together over long stretches of time.
Alongside fellow composer/directors Alex Mincek (saxophone/founding member), Sam Pluta (electronics), Eric Wubbels (piano), and performers Ian Antonio (percussion), Erin Lesser (founding member, flute), and Josh Modney (violin), Soper frequently tours, performs with, and writes for the Wet Ink Ensemble.
Her large-scale monodrama for the group, Voices from the Killing Jar, was released on Carrier Records in 2014.
