The Mestik (an elven-like creature) of Estonia is back. “Feral Hearts” is a beautiful, aural and visual, musical trip from the queen of Bubblegoth. Kerli is always a treat. On “Feral Hearts”, she is lighter but not less thrilling, more like a helium balloon rather than a boulder. Kerli has definitely won my heart. Listen to her. You’ll hear traces of Bjork and Sigur Ros all shook up into something very original.
