Not being familiar with Irish first names, it’s only when I looked at her entry on Wikipedia that I realized that it was actually HIS entry on Wikipedia. All the same, the only piece of Dennehy so far that I’ve heard and reviewed is his short “STAMP (to avoid erotic thoughts)” for string quartet, played by The Smith Quartet in their recital of “Classical meets Dance- and World-Music” pieces, “Dance”, on Signum Classics (2011). Robust, invigorating, and it includes actual stamping.
