I believe he still is, but doesn’t always apply himself as much as he used to. Some of the tracks on his recent albums do show that level of skill.
The Beatles’ “Hey Jude”, right around the 3 minute mark, where it transitions from “Better Better Better Better Better Better Ahhhhhhh!” to the Nah-nah-nah-na-na-na-nahh" refrain that the song is famous for. 
Also, same song, the chords that build up throughout the nah-na’s.
There’s a rather weird piece call *Cantus in Memory of Benjamin Britten *by Arvo Part. It is for strings and one tubular bell. If I tried to describe it to you it would sound boring, but it isn’t. The strings gradually reach a crescendo by the end of which the whole ensemble is playing A minor, very loud. The strings then fade away and all that can be heard “coming out from behind” the strings is the reverberation of the bell, which has been struck quietly while the strings are still playing so you don’t hear the strike. The bell fades and there is silence.
I could attempt to wax lyrical about what it all means and why it’s so good but I couldn’t do it without sounding wanky. You have to listen to it on a good pair of headphones in a dark room and experience it for yourself.
Suffice to say that knowing the name of the piece (and perhaps even otherwise) the effect is just stunning. I used to listen to it over and over again just for that moment where it all fades and the bell emerges and then dies away. It’s just… just beautiful man! Sniff.
