Even though the trilogy isn't yet completed, BTSX is undoubtedly one of the most capable and influential Doom community projects of the modern era. A large part of the tailored aesthetic of BTSX is its melodic, complex soundtrack. The music is at wistful, lonesome, and introspective. A more perfect musical expression of BTSX's colorful and haunting environs I cannot imagine, not to mention how outright listenable each track is. Overall just a great soundtrack.
