Query: intriguing,cathartic sound

Although the group has some trouble writing solid, memorable hooks, they have an intriguing,cathartic sound which makes I Have Much to Report a promising debut. Sully's music tends to be dark and very atmospheric. While it's often composed out of jamming, the resulting songs are very focused and intense. But at the same time, the vocals are usually driven by sound rather then lyrics.
