The Hallgrímskirkja in Reykjavík is an extraordinary building. And inside it there is an extraordinary organ. Playing that organ here is Christopher Herrick and this seventh volume of 'Organ Fireworks' presents the customary collection of splendour and devastating sound.

At the centre of the disc, and in a set of pieces to do with maritime misfortune (and particularly the sinking of the Titanic in 1912), is the Reubke Sonata, one of the masterworks of the concert organists' repertoire.
