On the Radar Brothers' third release, And the Surrounding Mountains, the Los Angeles trio -- Jim Putnam (vocals/guitar), Steve Goodfriend (drums), Senon Gaius Williams (bass) -- retains the guitar strummed, slow dirges that earned the band a slo-core tag. But And the Surrounding Mountains is a stunning collection of songs that build on that slo-core reputation literally. Keyboards, electric guitar and vocals are layered throughout as each song escalates to a peak and a final denoument.
