Equal parts crushing & 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 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 & solidarity.
