This weekend Mumford & Sons are playing two sold out shows at the Susquehanna Bank Center on Saturday and Sunday evening. WXPN will be broadcasting the Sunday night show live. Both nights there are two opening acts; singer songwriter Ben Howard and HAIM, three sisters from Los Angeles. Make sure you get to the shows early enough to see both opening acts. HAIM include Este, Danielle, and Alana, and drummer Dash Hutton. The sisters grew up in a musical family, raised on the classic rock leanings of their parents, and started as a band in 2006. They released their Forever EP in October 2012, have a fantastic new single “Falling,” and recently captured the prestigious BBC Sound of 2013 award. It seems that the UK has fallen in serious love with the band, and we’re expecting them to make a big splash with Mumford fans here in the States. The sisters sing in an urgent Stevie Nicks kind of way and there’s a percussive element of funky-ness to their songs. Their harmonies are sharp and to the point; the songs are high on melody and the delightful rush of pop candy (the kind that’s good for you). Last March at SXSW in Austin, HAIM received excellent reviews from the music bloggers and critics who covered the festival. HAIM will be on the air with Eric Schuman on WXPN tomorrow, Saturday, at 3PM. Tune in to learn more about them.
