I know nothing about opera. Nada. Zilch. Never been to one and, to broadcast my ignorance, know virtually nothing about them. However, I've read A LOT of comics and I think that I know a little something about storytelling, and I know that P Craig Russell is one of the grand masters.
The saga of Parsifal draws on Christian and Arthurian myths to tell of a hero's temptation and salvation. PCR fills the pages with imaginative, colorful landscapes, foliage and structures. I imagine that this was one of his earlier works, because the storytelling is solid, but not nearly as lyrical and elegant as his more recent work, and his figures are inconsistent (although still recognizable).
Two songs by Gustav Mahler are adapted next, and these two short pieces show some of Russell's range, as "The Drinking Song of Earth's Sorrow" showcases his ability to illustrate anything from a classic hero to a exhausted street corner, from a Japanese pagoda to a neon Vegas avenue. "Unto this World" is a lush piece done in what appears to be colored pencils, giving each image a soft, beautiful glow.
"Ariane and Bluebeard" is an interesting tale of the exiled/forgotten/murdered wives of fairy tales. The new bride, Ariane, sets out into the depths of the castle to rescue and redeem the exiled brides. Russell's art gives weight, beauty and majesty to a story that may not have otherwise survived the translation to a more straightforward narrative style.
Finally, I'd be remiss if I did not give some credit to Galen Showman for his excellent assist on the final adaptation, "The Clowns" from "I Pagliacci." Working from PCR's layouts (and under his inks), Showman penciled some of the most emotive characters in the entire volume, and his lettering truly carried the tale (I'm not sure who lettered the previous stories and the style is similar enough that it could have been Showman as well, but the changes in font and balloon shape in Tonio's prologue during "the Clowns" is one of the few times that I've noticed lettering in a good way!). And it's a damn creepy story.
Well worth it.
