On the album, Dudek is joined by pianist Hans Koller, double bassist Oli Hayhurst, and drummer Gene Calderazzo.

"[3] Stephen Graham of Jazzwise remarked: "Although clearly not cutting edge music as we understand it today, Day and Night is all about fine craftsmanship and the power of instinctive interpretation.

"[4] Writer Richard Williams stated that Dudek's playing "has the vigour — physical and intellectual — that you might associate with a musician half his age, although I think his exceptionally handsome tone has softened slightly over the years," and commented: "the repertoire is... well chosen...

"[5] Point of Departure's John Litweiler noted that although Dudek's "inspiration is Coltrane's early Atlantics... he plays a minimum of scales and double-time... his accents are dispersed, he swings freely over the rhythms instead of hitting downbeats Coltrane-style."

"[6] Writing for JazzWord, Ken Waxman stated: "the masterful readings of these tunes depends as much on the veteran's interpretations as the enthusiasm of the younger players... Steve Lacy once observed that 'Free Jazz keeps you young'.
