Mean, moody, magnificent Mari Lyn has finally (if posthumously) made her debut on DVD, thanks to the equally (if not more so) magnificent Donald Collup. Mme. Lyn, variously called “Hogcolleratura” and “La Traviyenta,” regaled the public access airwaves in the mid-1980s with a series called “The Golden Treasury of Song,” featuring the blond-bewigged “singing hostess” warbling her way through everything from “Casta diva” to “Ma Curly-Headed Baby.” Donald has anthologized La Lyn’s greatest moments (and worst quarters of an hour) into three DVDs that La Cieca is certain are destined to give this and future generations hours upon hours of delight. An audio clip of Mme. Lyn reading the letter from La traviata is one of the all-time favorite downloads from parterre.com, but, believe me, Mari Lyn is an artist who needs to be seen to be appreciated in her complete fulsomeness. La Cieca urges, entreats, and cajoles you go go immediately to Donald’s website to order these glorious documents of “the art of mal canto.”
