Anyway, as it's my wont to post occasional music videos, I'll honor the season, and my paternal grandmother's Roscommon heritage by stressing songs by Irish bands for the next couple of weeks.
Perhaps the first rock band to incorporate Irish traditional music (and mythological themes) into their music was Horslips, so thank them for such diverse groups as The Pogues, Black 47, In Tua Nua, and a host of other worthies (hell, U2's first album had the track An Cat Dubh on it, not a trad song, but one in Gaelic).
The song Dearg Doom (a mash-up of Gaelic and English best rendered as "Red Destroyer") comes from the band's 1973 The Táin album, a musical interpretation of the epic Táin Bo Cuailnge ("The Cattle Raid of Cooley"). The annotated Horslips lyrics page, besides giving a basic gist of the song's meaning, has a funny item about the genesis of the song (which is an unholy hybrid of traditional epic and Marvel Comics, conflating Cúchulainn with Dr. Doom), and a couple of nice quotes from Phil Chevron, a founding member of the Radiators from Space, who joined the Pogues for "Rum, Sodomy, and the Lash" and subsequent albums.
The blazing guitar riff that anchors the song is the traditional O'Neill's Cavalry (check out this sweet acapella version). The video reminds me of Spinal Tap's Stonehenge, because of the band's outfits, and the song's theme. I'd love to know if Stonhenge was inspired by this performance. Please note the chainmail "glove" and silver body paint on the lead singer's hand, a tribute to the divine king Nuada of the Silver Hand (known to HPL fans as "Hoary Nodens"):
Please note, this song became a number one dance hit in Germany. Who'd a thunk it? Additionally, in 2004, the Decembrists released an album titled The Táin.
