A young man named William Zauscher has created several entertaining videos available at YouTube. In the most memorable ones, he sings all the parts of the "B Minor Mass" (Dona nobis pacem, Sanctus, and Cum sancto spiritu) simultaneously, in split-screen, a rather impressive feat, especially the 6-part fugue in the Sanctus. The screechy soprano part in the Dona nobis pacem, eventually surpassed by a soaring violin track, can drive my cats from the room. Zauscher's facial grimaces (he sings on "noo" basically, without the syllables of the original text) and wild conducting are a stitch: the multiple versions of himself even interact with one another, which must have taken some planning. Besides Bach, he has strange takes on an excerpt from Puccini's Turandot (with a hilarious guest soloist), Death and Transfiguration, and the Chorus Mysticus from the Symphony of a Thousand. In the latter, the soundtrack is sequenced to corresponding snippets of the score and semi-orgasmic facial expressions (totally appropriate).
