by Tiana Feng At Sonic Boom Saturday morning, Grounders played to a varied audience of adults and hyper children. Andrew Davis’ warm vocals and the band’s jangly pop sounds were welcoming to all. It’s no wonder they have been signed to Nevado Records (home of Library Voices and Yukon Blonde). I remember the last time I saw them (probably a year or more ago) there was a laptop on stage, but this time there wasn’t one. I’m glad that they decided to do everything live.
