Tuesday the Sky

Jim Matheos, founding guitarist of legendary US progressive metallers Fates Warning,announces the release of the debut album from his new Ambient Instrumental R...ock project Tuesday The Sky. The first full-length album ‘Drift’ is set for release on June 30th, 2017, and sees Matheos expanding the boundaries of his sound ever further.

The album also features the talents of God Is An Astronaut’s drummer Lloyd Hanney, who provides a rhythmic backbone that is at once punchy, precise and restrained when necessary. Other guests include long-time OSI collaborator and former Dream Theater member Kevin Moore who plays keys on two tracks, and Anna-Lynne Williams (Trespassers William, Lotte Kestner) who provides ethereal vocals (of the non-verbal kind) on two other songs.
