Thank you so much! The only advice I can say is work hard and reach out to these people because all of them were kind enough to do this so take a chance! Call ins are easy to do and set up.
Agreed. I was in my second year of college radio back when Taylor Swift was essentially a no one so we reached out, had her in studio at WCUR before her gig at the student union and the rest is history. I don't think people in college/HS and have radio stations realize how easy it is to have guests anymore. Everyone is looking for free promotion and we always tried to reach out to help, even if the band didn't necissarily need it (like your list.. HTL, Chris C, WATIC, etc..). Some of the best days of my life.
