"John's music is a very hip classical music, in a way; since the bass and drums are playing more written functions. The whole conception of his composing is very special." - Lee Konitz

Marc Myers - JazzWax
"...an expert jazz adventure conducted with uninhibited respect."
"This music is addictive and beautiful, played with dedication and passion: challenging and intriguing, taking the jazz tradition on a step further into Schoenberg's 'emancipation of dissonance'."

"A synthesis of modern New York improvisation and serial technique; a muti-layered, artful music that always swings despite all the complexity and grooves.”

"O' Gallagher has long been associated with 12-tone music and takes the bull by the horns by adapting eight Webern pieces for his sextet plus voice. O'Gallagher is both mathematical and creative with his approach, staying close to Webern's melodic intention while trying to pull out the music's internal essence...The Anton Webern Project contains a wealth of riches that pays off with multiple listens."
