Warning: The following video contains footage of Bono singing along with (and annotating) himself; it may not be suitable for certain sensitive indie-rock viewers. But if you count yourself among those of us who are highly U2-tolerant, click here and check out this sort-of-almost-a-music-video for the band’s sort-of-almost-new song, “Wave of Sorrow.” The rough track was laid down during the Joshua Tree sessions circa ’87, but the vocal wasn’t completed until “a few days ago,” Bono explains in the clip, whenever it was filmed… and, as of his pep talk here, the rest of the group hadn’t even heard the finished tune yet. The 1987-meets-2007 studio version, which boasts but one Bono vocal, is due next week on a two-CD deluxe reissue of The Joshua Tree. Here, on videotape, he discusses the trip he and wife Ali took to Ethiopia that inspired the lyric, asks whoever is filming him to start playback, and then sings along with himself… adding little interjections about the meaning of various lines, and references to what sounds like “the sowlms” (which I believe is Dublin-ese for the Psalms). It’s fun to know that occasionally, even two decades later, a band that still couldn’t find what it was looking for on a particular track can finally find some resolution.
