‘Sound’ is a previous album artwork for a different line of music titled "EXTRA" that Gloria has created. It involves four raw acoustic pieces that reflect the experiences Gloria has felt through becoming betrayed and the emotions felt while witnessing other people becoming betrayed in relationships. The album also consists of five other experimental and electronic pieces. In "EXTRA", GLO aims to provide a positive impact on the audience with trademark coughs and unprofessional commentary in the hopes of being comedic and satirical.
