Sounds a bit like Alan Hovhaness and Philip Glass mixed together at times. It has the spiritualism of Hovhaness (and his bells and chimes) plus the minimalism of Glass. And actually, I preferred to the orchestral playing before the cello.
I am sorry but I find the orchestra far too heavy - although I love this concerto. I recommend Geringas' version, with the Riga Philharmonic orchestra conducted by Jonas Aleksa. This is a bit unfair for Barta, the cellist, who has a wonderful "voice", but the orchestra is simply not up to the challenge. Shame.....
