I know it's not their actual concert, but I do have a youtube playlist that has the pieces mentioned in the series here, along with some that I added that would be in a similar vein to Tetsuo's declared taste:

I'm also a huge nerd (in multiple ways) so I'm gonna eventually post a recording of a bit of "Sound of the Waves" that was shown in sheet music form in Vol. 3 XD
@Violistofhameln Cool! Thank you!
The thing I wanted to listen to the most is his original piece Tetsuo composed, which obviously is fictional. But it would have been cool if it was real. Thanks again for the link. Looking forward to checking it out. And if you can, send me a link when you post the sound of the waves.
