He’s bouncing his thumb off the D and G in a video of Blast that I’ve seen.
Yep, just saw that. Being able to slow down the video really helps!
The start of Blast! is one I sort-of figured-out previously, but that's a bit different from his typical licks on the high notes. I THINK it is the pops I like, but I can now deep-dive in the videos, now that I see the playback speed feature.
Mostly with Marcus it is his melodic style I like, but I have really been trying to understand how he brings-out some of those high notes.
