This is an interesting thread. Almost all of the Resonance and Elemental releases come from the period of Evans' deepest heroin habit: 1964-1970. He almost always still played well during that period, but sometimes it could sound almost like he was phoning it in. We have so many live recordings from that period that it is easy for something to sound rather generic. I do think that some of the Resonance / Elemental releases fit that category, although hearing Evans in (usually) good sound on those records can still be quite enjoyable.
In my view, the major exception to the above is the documentation by Resonance of the trio with Jack Dejohnette. That trio had a special sound, and I think that it inspired Evans. All we had until recently was the single Verve release of Live at Montreux. Thanks to Resonance, we now we have more than five times as much music from that trio, which is an important addition to Evans' discography (IMO).
