Concert review: Peter Bjorn and John put on a high-energy show at the El Rey Theatre

Peter Bjorn and John
_May 14, 8 p.m.
El Rey Theatre_

Pop-rockers Peter Bjorn and John may be most well-known for the whistled hook of their 2006 hit “Young Folks,” but at a sold out show at the El Rey Theater on Saturday night, the Swedish trio showed that it knew how to do much more than make a catchy single; it also knows how to put on a terrific live show.
