Henrik Jensen‘s ‘Followed By Thirteen’ (1st show)


Esben Tjalve – piano

Henrik Jensen – bass

Pete Ibbetson – drums

Unfortunately, due to unforeseen circumstances, Iain Ballamy is no longer able to join the trio for this performance. 


Double Bass player and composer Henrik Jensen released his third album Affinity on Babel Label in March 2020, a collection of incendiary tracks performed by his quartet Followed By Thirteen.

Their 2016 album Blackwater received a wide range of complimentary accolades from The Guardian, Evening Standard, London Jazz News and various other influential critics. Affinity is a whole new proposition, generating an emphatic, melodic sound and lyrical flow in celebration of the Double Bass.

​Building on the work done by other great bass band leaders like Dave Holland, Charles Mingus and Drew Gress. Followed By Thirteen is an ensemble of musicians at the top of their game and who deeply respect each others individual merits and sensitively represent each part.
