Concertreview van Concert in Ainsi Jazz Maastricht op 9 januari 2020 in Jazzflits
door Mathilde Löffler (27/1/2020)
“This approach resulted in an enjoyable jazzrecord where inventiveness, jumpiness and sometimes absurdity come together. For instance in beautiful harmonies between cello and soprano sax.”. If you pay attention, you can hear the birds sing in your living-room.”

With his 5th album ‘Spark’ Ad Colen gives a new fresh sound and touch to the somehow traditional jazz quartet. A Cd with interesting compositions and catchy melodies.
De Limburger XXXX by Paul van der Steen
“.Colens sound and compositions are gaining more and more expressiveness with each CD he’s makes. He sounds fresh, to the point and relaxed. In the meanwhile he creates nice surprising hooks and barbs so the music never gets boring”.
Volkskrant XXXX by Tim Spranger (Spark)
:Also on this album the music is nononsense, straightforward without too much decorations. The harmonies alway move in a nice way asnd the cheerful grooves make you wanna jump from your chair:”.
Jazzreview.com (USA) by Randall Parrish
“Free is the title of the fourth release on the Sweet Briar Music label for the Ad Colen Quartet. Covering a wide-ranging scope of tuneful sound-vistas, this newly restructured Dutch Jazz Quartet put forward a collection of compositions imaginatively full of richness and depth. The title Free is appropriate. The Ad Colen Quartet are unobstructed by any restrictive limits, and stretch out to meet whatever creative artistic ideas best suit their jazzy endeavors.Free is sophisticated and full of powerfully involving pieces which exhibit a sense of unity and, in my mind, classify as works of art. The Netherlands has reason to be proud of groups such as The Ad Colen Quartet. They strive as “keepers of the flame” to make sure that the Jazz tradition is kept alive throughout the globe”.
Jazzpodium (Germany) March 2010 by Markus Koehler
” Ad Colen is a saxophonist living in Utrecht, and is one of the best examples that at least in the Netherlands, jazz is as alive and well as it always has been, and has no worries about new strength to drive it forward. The Ad Colen Quartet is not in Europe to merely faithfully reinterpret American jazz greats, be they alive or dead, or even to assist them if the need arises…. they have broken free.
This ensemble also delivers more than just time-keeping and harmony for the soloist – they dialogue with the soloist, rein him in or let him fly. They turn the group on its head and you have to ask “Who’s the leader here?” This leads to an electrifying album of a soloist and an ensemble with genuine personality”.
