TIL was standard on the setlist from 2016-2018, since 2019 they haven't played it until this year.
I've never been a big fan of his solo on TIL (most of the time he looked like he didn't care), except for a couple of exceptions, DJ Ashba's solo on TIL is better for me. But I'm a fan of his solo on TWAT, seems like he listened to Buckethead's solo this year and now it sounds very good.
