I'd go see Santana, Beck, The Offspring and Fall Out Boy. I'm 54 and I think these artists would play to some of my musical tastes from the past 50 years.
A couple months ago I saw the Red Hot Chilli Peppers and Muse in Vegas. The Peppers were a real good show and the fact that they played in Allegiant is a testament to their fan following and popularity. The older crowd was really into it and I enjoyed it a great deal.
But Muse...... damn! They played in T-Mobile which was my first time to see them and what a show they put on. The energy of the band, the much younger audience, the songs and the production were incredible. That sort of show really invigorates me and makes me feel like a 20 year old all over again. That's one of the main reasons I still like going to shows, these younger acts are just so energetic and the enthusiasm is infectious.
