The heroes are tired of cello

Well, after a first listen, this album disappointed me.
Apart from the song 'Sacra', everything else is soup; The cello is reduced to its simplest form, the (too) many collaborations lead to horrors ... all gives the impression of an album that accumulates subtractions:
No thread, no soul, no lyricism and almost no genius.

What has happened? the source has dried up?

PS: thank you to streaming sites (of course legal) for having spared me this purchase.
