It’s been a minute since I last pondered the Fray, the mid-’00s kings of piano-pop ballads. Six years ago, the Denver group’s overwrought Applebee’s rock was going head-to-head with Coldplay and Keane in the battle for the sensitive spots on sorority girls’ iPod playlists. That momentum appears to have dropped off these last few years, but all it takes is another hit, which might come on the band’s third LP, due out in early 2012. Perhaps there will be some teases of new material at this show. I also suspect a moment when the singer falls to his knees and sings an especially poignant lyric.
