Rialto Theatre is delivering a pair of concerts on New Year’s Eve Sunday, Dec. 31, which is actually pretty cool: While live music is a big part of a number of New Year’s Eve blowouts, stand-alone concerts tend to be pretty rare.

So here’s the hard part: Which to see? Here’s a little primer to help you decide.

• At 9 p.m. Sunday, Brian Lopez and his XIXA bandmates join DJ Dirtyverbs for a big cumbia blowout party “Arizona Amazonica” NYE 2018. It’s an all-ages affair and it’s one of the few times we get to see XIXA since their European summer tour. Tickets are $12 to $50 through ticketfly.com (Wanna catch up with XIXA? You can get a live version of their 2017 album “Bloodline” at xixa.bandcamp.com.)

  • Also at 9, the classically-trained Tucson psychedelic prog-rock band The Bennu is kicking 2017 to the curb and cheering on ’18 with Woke Up Dead at the Rialto’s offshoot stage, 191 Toole, 191 E. Toole Ave. This is for adults only, 21 and older, and admission is $8 in advance at ticketfly.com, $10 at the door.

Meanwhile, if you’re looking for a traditional New Year’s Eve shindig with a band, check out Casino del Sol, 5655 W. Valencia Road; Desert Diamond Casino, 1100 W. Pima Mine Road; or the Maverick Live Country Club, 6622 E. Tanque Verde Road.
