Slip into Slide Slam tonight at Barrio Brewing

Some architects and designers could talk about their projects and their artistic philosophies for hours.

But they won't get the chance at tonight's Slide Slam at Barrio Brewing Co.

At each Slide Slam - this is the third one - four artists, architects, and/or designers come together to present their work and design ethic in only 15 minutes each.

Hosted by the Southern Arizona American Institute of Architects, the show starts at 6 p.m. and will feature these presenters:

• Henry Tom of Line and Space Architects.

• Lisa Robinson, a photographer.

• Bil Taylor of Taylor Design-Build.

• Nicholas Burke, a sculptor.

The presenters will show slides and talk about their residential and public architecture, sculpture and photography.

Organizers said more than 70 people attended each of the first two Slide Slams, which were held at Barrio Brewing and Tooley's Cafe.

Slide Slam will be held in the back room at Barrio, which is downtown at 800 E. 16th St.

Admission is free.

Megadeth will rock the Rialto Tuesday

When Megadeth considers its legacy in the world of thrash metal, it goes straight to 1990's genre-defining album "Rust in Peace."

The band dusted off that record and is playing it track by track, along with some other Megadeth favorites, on the tour that kicked off March 1 in Spokane, Wash.

The "Rust in Peace" 20th Anniversary Tour - which also includes Exodus and Testament - pulls into Rialto Theatre Tuesday for a sold-out show. Testament is slated to play its disc "Legacy" cover to cover.

The concert in many ways gives tribute to Megadeth's past while looking to its future.

The outing reunites founding vocalist Dave Mustaine (right) and original bassist David Ellefson for the first time since Ellefson left the band in 2002. Shawn Drover and Chris Broderick round out the lineup.

Mustaine and Ellefson's friendship dates to 1983, when Mustaine, freshly booted from Metallica, formed Megadeth.

Tuesday's concert is an all-ages show; doors open at 6:30 p.m.

'Hannah Free' screening at Loft to benefit Wingspan

Sharon Gless plays the title character in "Hannah Free," a love story screening at 7:30 p.m. Tuesday at the Loft Cinema.

Gless (you know her from "Cagney and Lacey" or maybe "Burn Notice") plays a free-spirited World War II vet who has a long-term affair with a more conservative woman.

The 2009 movie has won awards at several gay film festivals.

Tickets $10, with proceeds going to Wingspan. There's a patio reception at 6:30.

Last season of 'Saving Grace' starts Monday night on TNT

The cliffhanging ending found Oklahoma cop Grace Hanadarko (Holly Hunter) flat on her back from a multistory leap of faith with a woman who shares her guardian angel. Monday's fourth and final season opener shows Grace no worse for the wear. But she's chasing a looming suspicion that she's on borrowed time with too many questions ("What do you want from me, God?") left unanswered. Will Grace find redemption, or die trying? "Saving Grace" airs at 10 p.m. Mondays on TNT.
