Ok so cello music it is. I absolutely love cello to the point where I nearly regretted later on to have chosen piano instead of cello. In the end, I just adore both. Anyways, those guys, Break of Reality, are really interesting. They have a modern sound and work with a drummer which had a nice rhythmic texture to their quatuor. I'm just putting this composition I found dynamic enough to avoid the melancholic tune which could be associated with cello:
