Tim states that this is his "most adventurous piece so far" and I think it's a fabulous toccata on the well-known Palm Sunday hymn, "All Glory, Laud and Honour". The descending arpeggios drive the piece as an accompaniment to a Tuba, Trumpet or whatever solo stop you have on offer! The score is available for instant PDF download below.
