I like Sarah Mclachlan enough, like most other soft-rock tolerant folk, but I was not expecting the truly impressive show she delivered Tuesday, April 19, at the Bank of America Centre. Since Mclachlan mentioned it had been seven years since the band strolled through Boise, it's likely that gap will shorten in the future after the powerful performance garnered up two encores from the packed house. The thing I realized about experiencing a Sarah Mclachlan concert live, is (a) you already know most of her songs-they're all hits to some degree; (b) almost all are love songs with such truth in the lyrics, her live emotional rendition makes these truths even more apparent, and (c) she has an amazing vocal range (even after suffering from larangitis-is it going around?-cause Elvis Costello postponed his show a week ago for the same reason). Songs I've been humming to for years suddenly took on new meaning, and I was surprised to find the show an incredibly emotional, almost tear-jerking experience for me and the others I knew present. My only complaint was when the beginning strains of Peter Gabriel's "Solsbury Hill" began, a personal favorite of mine Mclachlan's band did justice to, but her voice and energy lacked the passion necessary to match Gabriel's classic. Yet as passion was evident throughout the rest of the performance, I appreciated her version for what it was and decided to belt it out better myself sometime in the future, in the privacy and relative anonyminity of my car, of course.
