   • 2007 March 9, Jon Pareles, “Three Bands on Trips That Lead to the ’60s”, in New York Times‎:

     Mr. Droste is usually the more ethereal, with the sweeter voice and the gentler melodies; he was the one strumming an autoharp for “Lullabye,” while Mr. Bear tapped a glockenspiel, and Christopher Taylor played a flute.
