The techniques, Hendrix was innovating so hard on all of his albums. His first album was basically taking the outdated R&R of the time and adding psychedelic flavor. The second two albums created a lot of techniques that later became standard. I remember I read a post by quest talking about how he wishes he could've seen what Hendrix would've done today (basically stating that being as he blew people's minds innovation-wise back in the late 60s, with the technology out today.....). This is just counting studio-innovation, not even considering his live act and his beautiful mentality when it came to life, the world and music displayed in his interviews. I get choked up watching those.
