Viola, lap steel guitar and banjo, along with piano, traditional percussion and lovely, delicate vocals, make up the sound of local musicians Buried Beds, named “Best Band 2004” by Philadelphia Magazine. The group fuses an indie rock sensibility with the sorrow and beauty of Appalachian songwriting. One review called the music “angsty, heart-on-the-sleeve melancholia that sounds both winsome and wise.” These successful locals—part of the West Philly denizen of musicians, artists and creative types who make up the New Planet Collective—play two shows in very different venues this month. First, they’re the musical guests at Kelly Writers House on Dec. 12 for a night of conversation between WXPN host Michaela Majoun and women music writers. Then, on Dec. 23 at World Café Live they’ll play a 7:30 p.m. show with fellow local acts Anne Heaton and Bebek.
