On the second installment of the Stagecouch Concert Series, Sara’s Soundcheck staple QueenEarth croons on the couch. Backed by some whistling winds and the drum of raging rain, QueenEarth sang  three songs.   She provided musical precipitation with “What If,” “Stargazer,” and “All of Me.”  The thunder thoughtfully responded to the music she was making and the storm had enough fury to make the lights flick off and eventually knock the power out, but it was QueenEarth that was electric, a terrific tune tempest, a gust of good music.
