Standard deviation

Two decades have passed since SONS OF RA emerged onto Chicago's scene with their fusion of heavy prog, jazz,math rock, and elements of avant-garde. Initially a line-blurring experiment based on improvised music, the trio has proven that the itchings of jazz fusion aficionados and math/progressive rock/metal purists can both enjoy the samemusical relief.The band independently released four EPs since 2016, culminating with the critically acclaimed six-part suite Tropic of Cancer in 2024.Now, SONS OF RA evolves with their full-length album debut Standard Deviation, diving deeper into roots of avantgardejazz, fusion, math and progressive rock while maintaining a powerful metallic crunch. The album features interpretations of compositions from jazz legends Carla Bley, John Coltrane, and Don Ellis, balanced with a collection of original compositions reflecting the groups diverse influences.Standard Deviation was recorded and mixed by Spenser Morris (Saor, Panopticon) and mastered by Grammy Awardwinningengineer Alan Douches. The cover art is a commissioned painting by Chicago-area artist Nick Gurley.
