Steven Wilson has been revisiting his earlier 5.1 mixes of classic Tull, Yes, etc., albums, adding new 5.1 and Atmos mixes to these reissued discs. Several are out already, with more on their way.
I compared the previous "definitive" 5.1 mix of "Larks Tongues" with the 2024 version and although both sound good, they are fairly different at times.
