- The Village Voice

"No series called Gashole could take itself too seriously, and that’s part of the appeal of Karen Mack and Michael Holland’s gleefully goofy, shamelessly entertaining neolounge act. For five years, Mack and Holland have been resurrecting the lost art of the medley, with an emphasis on pop hits from the ’70 and ’80s; the summer-themed opening number of their latest show, Blend-O-Matic, includes bits of songs by acts as varied as Sly and the Family Stone, Genesis, Eddie Cochran and Richard Marx. The inventive Holland supplies the musical connective tissue on piano or guitar, as he and the supple-voiced Mack blend their vocals into surprising counterpoints and ornate, often lovely harmonies. And have I mentioned the gong and the fog machine? Everybody had fun; everybody Wang Chunged!"
