Seeing Peterborough roots orchestra the Silver Hearts live is exhilarating by virtue of the sheer spectacle of the band - 10 -plus musicians in snappy black suits busting out tunes with sweaty, infectious energy. Our Precious City, the Hearts' second disc, sucks you in with the same haphazard charm. Recorded with a homespun vibe on an analog Neve Board, the album spans styles ranging from wheezing klezmatic swing to bluegrassy ballads to cabaret jazz (Kurt Weill's creepy O Heavenly Salvation, one of two covers, is a remarkably good centrepiece). While some of the vocals aren't quite up to the calibre of the Silver Hearts' musicianship, it's a testament to their strength as a band that they squeeze a staggering 17 short 'n' sweet songs into 45 minutes without a single throwaway track in the mix. The Silver Hearts tear up the Silver Dollar as part of the Downtown Jazz Fest Friday (June 25).
