{"product_id":"standard-deviation-763232401426","title":"Standard Deviation","description":"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 itching of jazz fusion aficionados and math\/progressive rock\/metal purists can both enjoy the same musical 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 their roots of avant-garde jazz, 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 group's diverse influences. Standard Deviation was recorded and mixed by Spenser Morris and mastered by Grammy Award-winning engineer Alan Douches. The cover art is a commissioned painting by Chicago-area artist Nick Gurley.","brand":"Free Electric Sound","offers":[{"title":"Default Title","offer_id":46373160845395,"sku":"2698959X","price":15.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/1937\/5187\/files\/4402696_149659ce-fa70-4b22-a70e-afd77d7e1d18.jpg?v=1790417684","url":"https:\/\/www.deepdiscount.com\/products\/standard-deviation-763232401426","provider":"Deep Discount","version":"1.0","type":"link"}
