A handful of lawn tickets remain for what is looking like one of Tucson's biggest concert weekends of the year - Florida Georgia Line at Casino del Sol's AVA.

But the chart-topping duo's Sunday show is just the finale in what could be the biggest weekend of the year for the venue at 5655 W. Valencia Road.

AVA will host back-to-back concerts starting with "The Red Rocker" Sammy Hagar Friday night, Matchbox Twenty on Saturday and Florida Georgia Line on Sunday.

It's the amphitheater's busiest weekend of the summer. Tickets are available at tickets.solcasinos.com .

• Sammy Hagar

8 p.m. Friday

Premium reserved seats - the ones closest to the stage - are gone; $50 will get you a seat toward the back of the reserved section and $30 gets you a spot on the lawn to hear the 65-year-old rocker belt out his signature driving anthems, including "I Can't Drive 55" and "Poundcake." Hagar will also bring in a few of the hits from his various bands over the past 40 years, including Van Halen and Chickenfoot with former Van Halen bassist Michael Anthony. (The pair also are in Hagar's band HSAS, featuring former Journey guitarist Neal Schon.) This will be Hagar's first Tucson show since May 2011 , when he played the AVA. That's also where he appeared with Van Halen (2004) and Chickenfoot (2012).

Pop-rockers Matchbox Twenty

8 p.m. Saturday

The on-again, off-again Florida alt rock/pop band makes its first Tucson appearance since 2003, and happily all but one of the founding members, including frontman Rob Thomas, are in tow. That show at Tucson Arena was Matchbox Twenty's only Tucson show, and it came as the band took its first hiatus; it has taken another since then. The group reunited in 2011 and released the Album "North" in September. Lawn tickets ($30) are all that remain.
