One-track albums are ridiculous. But seeing as how Mike Patton has pretty much defined his career as the crossroads between the ridiculous and the radical, the fact that all 55 minutes of "Delìrium Còrdia" are packed into the single "song suite" titled -- you guessed it -- "Delìrium Còrdia" shouldn't be all that surprising. (After all, this is a group whose first album was 30 songs long, so why not explore the opposite extreme?) What's most shocking about "Delìrium Còrdia" is how creepy it is. The spooky ambience of their debut disc and the tongue-in-cheek "covers" of themes from films ("The Omen," "Twin Peaks") on their "Director's Cut" album gave ample evidence of how dark this all-star conglomerate could get. But the relentlessly dark vibe of "Còrdia's" pounding and twisted atmosphere is doubly effective when coupled with the all-in-one-sitting insistence of the CD. Maybe it's not so ridiculous after all.
