In April of 2010, 'Projection Bias' a group show exhibiting some of Courtney's video work took place at Antenna Gallery in New Orleans. The show featured a variety of Sell's experimental short films on two projectors, images slightly overlapping. Included within the work was Sell's 'Erotic Symphony' series, as well as his shorts 'Valentine's Day', 'Swamp Dance' and 'I am Transparent'. Regarding the show, Fabric Magazine wrote:
"Sell’s piece Erotic Symphony is a mash up of two videos. It shows documentation of a man in a transparent plastic mask awash in abstract layers paired with video footage of VHS porn edited to little more than fuzzy black and white images. The idea behind it being that, although bodies are not obvious in the abstracted pornos, the movement will still be there. Sell explained that he intends to “challenge notions of erotica” with these masked images."
'Sell's 'Erotic Symphony' melds innocent, everyday images and porn-inspired sequencing in a video diptych reminiscent of early Stan Brakhage.'
