“Herwig Zack is a remarkable violinist whose tone is steady, whose virtuoso apparatus is balanced with the warmest artistry and whose willingness to explore is admirable. He is another Milstein in the making.”

(Rob Barnett, MusicWeb International 03/2008)


“The Frankfurt-born Herwig Zack, former concertmaster of the Stuttgart Chamber Orchestra, is an established master. His beautifully idiomatic playing, tinged with a sense of frailty and vulnerability, is matched by a maturity and experience appropriate to a former pupil of Max Rostal.”

(Roderic Dunnett, The Strad, May 2008)


“Er ist einer der stillen Stars an deutschen Musikhochschulen, die keine hektische Weltkarriere gewählt haben: Herwig Zack lehrt seit 1994 in Würzburg – und besitzt offenbar fast grenzenloses Einfühlungsvermögen. Bachs legendäre “Ciaccona”-Partita, Ysaÿes “Ballade”, Bartóks Sonate (1944) und die von Nikos Skalkottas ergeben samt Kreisler-Zugabe einen Blütenstrauß purer Perfektion”

(Johannes Salzwedel, Kultur SPIEGEL, Februar 2009, Heft 2)


“The Strad recommends: FOUR STRINGS ONLY: An absorbing celebration of the solo violin.

This disc is really very special. Almost 80 minutes of music for unaccompanied violin might put off  all but the most devoted listeners, but the CD's conception and performance, not to say its erudite booklet notes, all by the German-born soloist…and teacher Herwig Zack, create an experience that grips from start to finish. Zack's playing is serious-minded, assertive and demonstrative, and he has a thrillingly flexible tone that ranges from the thin and piercing to the dark and brooding. He is generous yet unassuming, and it seems as though each note he plays is carefully considered, weighed, and delivered with a sincere intention. His intonation is immaculate, and his phrasing is a joy to hear. The Bach A minor Sonata is intense yet clear-headed: Zack is gloriously articulate in the Fuga's intertwining contrapuntal lines, yet he brings a restless energy to the dancelike demisemiquavers of the concluding Allegro. The two Bloch suites reveal Zack's more fantastical side: he's not afraid to rise to the drama of some of the writing, with huge swells of intensity and some finely controlled diminuendos, but he never overplays things. He shows off his wide-ranging tonal colours in the Middle Eastern-sounding sonata by Israeli composer Paul Ben-Haim, and the Berio Sequenza VIII bristles with fiery intensity.”

(David Kettle, The Strad, July 2011)


“…truly striking. The contrasts in tempo, texture, and color achieved are not only idiomatic for the composers' wishes, but indicative of Zack's well-earned reputation. The sometimes daunting technical demands are tossed off with ease. Zack takes risks from start to finish.”

(Mike D. Brownell, AllMusic Guide, August 2011)


“An excellent, revealing programme, chosen with intelligence and a more than worthy successor to Zack’s Catoire Avie disc…you will find this a pungent recital, dashingly delivered.”

(Jonathan Woolf, MusicWeb International 04/2009)


“Zack tempers his performance of the daunting Bartók Sonata with insight and even wit, and even Oistrakh didn’t bring to the Ysaye Ballade the vibrancy with which Zack plays it……Urgently recommended.”

(Robert Maxham about ESSENTIALS, FANFARE, issue 32:6, July/August 2009)


“I urgently recommended Zack’s first solo recital, and there’s little reason for diminished enthusiasm for this one. Urgently recommended, therefore, once again.”

(Robert Maxham about 4 STRINGS ONLY, FANFARE, issue 35:1, September/October 2011)


“A valuable collection of solo violin works from a very impressive violinist.”

(Andrew Morris  about 4 STRINGS ONLY, MusicWeb International, 10/ 2011)


"El ilustre visitante demostró un virtuosismo excepcional, que arrebató al público."

(El Mercurio, Santiago de Chile, 5.8.98)


"Playing to perfection...A remarkably talented player."

(South China Morning Post, Hongkong, 23.11.82)


"C'est un beau soliste, fin, classique, nanti d'une technique brillante et dont la musicalité distinguée se révèle par un jeu d'une grande purité et d'une expressivité harmonieuse et prenonte. Il fut le triomphateur de la soirée et le public lui fit une ovation."

(L'Alsace, 29.6.84)
