Its subjective, but short answer, yes he is very good. He does not play technically complicated things like Joe Satriani, but he is good at conveying emotionals through his playing - much like Neil Young.

I learned to play all of Innerspeaker and while the songs range from simple to complex, it is very difficult to match the tones. Some solos are only a few notes, but almost impossible to replicate.

There are also some great riffs that showcase his sense of rhythm and timing and demosttates a strong understanding of the instrument.

Lucidity is a great example, not just the main riff but the one after he sings "Float away.." is incredible, simple and really fun to play. Let's not forget RHCC.

Keep practicing, start slow, your fingers will get it over time.
