Guitar One Magazine "readers voted Mr. Grassel 'One of the ten best guitarists (you probably don't know) in America...' Years of study with George Van Eps, Tal Farlow, Jimmy Wyble, and Billy Bauer helped him create his own unique style."


JazzTimes Magazine: "Guitarist Jack Grassel may be the best-kept secret in the jazz guitar community (although aspiring players may know him from an instructional column he contributed to Guitar Player Magazine for many years). An astounding technician with remarkable fluency and speed on single note lines and an incredibly advanced harmonic vocabulary that is on par with the likes of chordal geniuses Ted Green and Lenny Breau. Grassel has continued to fly under the radar while quietly putting out the occasional guitaristic gem from his home base in Brewtown". (Bill Milkowski)
