How does a band reach the pinnacle of both commercial and critical success, dominate the airwaves for a handful of years, only to disintegrate into the ether? That’s probably the question that has haunted the members of Līve for two decades now. The band’s second major album, “Throwing Copper,” was omnipresent on both pop and alternative radio. The video for “Lightning Crashes” was an MTV staple. And then? Poof! After some 8 million albums sold (and a couple of moderately successful follow-ups), they were seemingly gone from the radar. (It could have to do with the fact that in this Google/SEO world, the name “Līve” does not render easily on search engines. Shoulda thought that through, boys!) It’s a shame, really. “Throwing Copper” is everything good about quintessential 90s rock, highlighted by singer Ed Kowalczyk’s mystical/nebulous lyrics.
