July was a hot month for music in Denver with events like the Global Dance Festival, Taylor Swift’s Eras tour, and the Underground Music Showcase taking center stage. But it also saw a serious effort by mega-music promoter AEG Presents to prevent drug overdoses at concerts. Since June, AEG has helped distribute thousands of free doses of the anti-overdose drug Naloxone as part of its partnership with the Keep the Party Safe, a UC Health-sponsored campaign aimed at educating people about overdose prevention. The campaign gave away 1,100 fentanyl test strips and 1,800 Naloxone doses during the July 28-30 Underground Music Showcase, a spokeswoman said Tuesday.
