“One of the most dynamic forces in Irish jazz, on and off the stage” – the Irish Times
“A European jazz artist of growing charisma” – John Fordham, the Guardian

This two-horns-no-chords quartet was established by drummer Matthew Jacobson in 2007 as a creative outlet for his compositions as well as his somewhat perverse fascination with anagrams. While he failed to find such avid fellow followers of wordplays, he did find and enlist the help of improv and rhythmic specialists Derek Whyte (bass), Nick Roth (alto sax) and Colm O’Hara (trombone).

The band play all original compositions from Jacobson (“a European jazz artist of growing charisma” – the Guardian) with influences as diverse as Charles Mingus, the Books, Deerhoof and Tim Berne. The formula for putting all this together in one palindromic setting is downtown grooves with catchy riffs, interlocking melodies and collective improvs.

ReDiviDeR have recorded three albums for Diatribe, Ireland’s leading record label for new sounds. ‘Never odd or eveN’ was released in November 2011 to a four-star review in the Irish Times and a “one to watch out for” recommendation in All About Jazz. ‘Meets I Dig Monk, Tuned’ was released in October 2013 and has been called “an inspired endeavour” (No More Workhorse), “a big leap forward” (Marlbank) and “a striking musical collage… recommended for those generally disposed to imaginative, genre-bending music” (All About Jazz).

Having taken a brief sabbatical from public performances following their second album, the group developed a new approach, aiming to give maximum freedom to each of the musicians’ considerable improvisatory instincts, while still retaining Jacobson’s penchant for off-kilter grooves and interlocking melodies. The resulting album ‘Mere Nation’ was launched at New Music Dublin Festival on the 29th February 2020 and has been described as “a colourful box of delights” (All About Jazz) and “yet another document of this fabulous quartet and their way of rethinking jazz” (Bernard Clarke, RTE Lyric FM)

The group have performed extensively across Ireland and the UK as well as touring and playing festivals in France, Italy and Sweden.
