The only ones that hold up for me, are he Shadofax releases.
First of all, they have more complexity and band interplay than most of the others I have heard, and since they originally came from the prog genre, they still retain quite a bit of their proginess for me.
Their frist release on Passport records, was a full on, intense, complex, chops laden prog album. Far from the toned down releases they did for WH.
And even when I saw them play live, after their 2nd WH release, they played all the WH material with substantially more intensity than on the recordings. It’s like, you could tell where their hearts were so to speak. More intense proggy fusion, in other words.
