“Equal parts crushing and cathartic, Marrow Deep, finds GRAMMY winners Mastodon pushing their sound into new depths without sacrificing what makes them one of heavy music's most forward-thinking forces. Mastodon channel profound grief into one of the most emotionally charged albums of their storied career. A 13-song testament of the effect those close to us can have on our lives—effects that can extend well beyond the time we have with them. An album ultimately representing resilience and solidarity.”
