"Neptune is essentially an acoustic chamber ensemble, with decidedly imaginative, adventurous leanings and - not surprisingly - a well-schooled sense of how to play jazz. It's the sort of outfit musicians love to play with, and it can be magical live; but "Thaw's" success is measured by how strong the writing is and how well it's all captured on CD."

"The Neptune Quartet features acoustic bass, cello, guitar and mandolin. If you attended the Toronto convention you had the chance to hear them in concert and might also have attended their excellent workshop on Latin rhythms. In addition you might have encountered them anchoring late night jam session that were notable for their interesting choice of tunes and friendly atmosphere.

Don is one of the very few mandolinists attempting to deal seriously with the language of jazz as it has developed since 1960. His compositions speak this language without sounding angry or harsh and the Neptune Quartet plays this music, along with tunes by Rahsaan Roland Kirk, Django Reinhardt and Lennon-McCartney, in a beautiful way. Glenn Wolff's rock solid bass playing lends gravity to the music while Julin's light touch often creates the sensation that the music is floating."

"...our region's answer to such avant garde, nationally-touring acts as the Kronos Quartet or the Turtle Island String Quartet. The Neptune Quartet is currently packing Poppycock's restaruant in downtown Traverse City on weekend nights, ripsawing the air with breadcutter string patterns that ring with a dense, crisp texture and power. It's string music on a knife's edge with a hammer swinging down swift and hard behind."
