on the topic of the Rock Music changing and Russ refusing to play it, bascally it's the "Grandpa Simpson effect" and Russ used to be with it (in this case 1980s hair metal rock) then they change what it was (to Grunge and later Nu Metal, post grunge and other forms of today's rock) and then what the it that Russ was with isn't it anymore and what it is seemed weird and scary to him and it is all happening to us eventually. the it in question is the sound of Rock Music in general, today's Rock is starting to become not it to me and what it's becoming is starting to seem weird and scary to me.
Grandpa Simpson's quote sums up what we viewed as our "age of new rock" and aging out of it for the new generation and this generation of rock isn't strong enough to sustain a successful hard rock station in a market that the white demos that kept it alive has been replaced by Latinos who listen to Spanish language music, people of African American descent listening to hip hop and R&B, the youth listening to Top 40 as well as Hip Hop and other youth friendly formats, and the fact most white people here in this area would listen to Kiss FM, Jack FM, Lonestar, and maybe Star 102.1 and 102.9 Now as well as classic rock on Lonestar 92.5.
Today's rock isn't mainstream enough to play, is pretty much entering a period where the only way to hear it on the radio in Dallas is via internet connection, HD Radio (if iHeartRadio launches a HD2 station on 97.1 or 92.5 that can cover the loss of The Eagle), or Sirius XM and their radio channels devoted to Rock formats, and for concerts of the major names, i would say just personally follow your favorite bands on social media and their websites for details of their touring schedule and also for local bands, you do the same but also if you want to discovered them, go to the local music places they perform at like bars, clubs, and other music venues. and just crank it up on what ever streaming platform or Sirius XM you listen to for rock.
