Other projects developed by Cahill include Playdate, Bay Area Pianists and Garden of Memory. Playdate is a group of commissioned pieces about childhood combined with classical works; the commission of an evening of new scores for four hands by Terry Riley, performed with pianist Joseph Kubera; and a concert of recent Italian music, featuring premieres by Luciano Chessa, Andrea Morricone, and others. She founded the Bay Area Pianists in 1993. In 1996, in association with New Music Bay Area"," Cahill created the annual Garden of Memory walk-through concert at the Julia Morgan-designed Chapel of the Chimes wherein audience members move through the environment with new music ensembles performing simultaneously throughout the spaces. In 2003 she co-curated the Berkeley Edge Fest at Cal Performances.
