Andrew Polk, Bob Cocke and Barbara Jo McLaughlin Exhibition

These three Tucson artists are far from ordinary. One paints abstract acrylics, another calls himself a “”magical realist,”” and the third makes sculptures out of recycled wood, fiberglass and chicken fencing.

Kittie

There is one reason to go see this all-female heavy metal band: it is working hard to combat gender stereotypes in the music world. In today’s society, women can suck too! 7:30 p.m. $17.25 in advance, $19.25 day of show. The Rialto Theatre, 318 E. Congress St.

“”World Harmony: Can It Happen?””

If you come early to this taping of a local TV program, you can be on the show. This week, the topic is the 2006 Tucson Peace Fair and Music Festival. It may not be Pets on Parade, but I’m sure it’ll attract some kind of audience. This is your chance to be a star! 6 p.m. to 7 p.m. Free. Access Tucson (Studio A), 124 E. Broadway Blvd.

This is a lecture about a post-World War II photographer who developed an interest in architecture. 5:30 p.m. Free. Center for Creative Photography

Immortal Technique

This rapper claims that his metaphors “”are like dirty herpes, but harder to catch.”” I think he’s right. Do you have any idea what the hell that means? 8 p.m. $16 in advance, $18 at the door. Club Congress, 311 E. Congress St.

Pima County Fair

This fair is kind of like the Arizona State Fair, except it’s smaller and nobody’s been shot. I did hear that spinning Galactatron can be a bit dangerous though. 11 a.m. $7. Pima County Fairgrounds, 11300 S. Houghton Road

Night of Canadian hip-hop acts

When I think of tough street cred and pimpin’, I think of Canada. Everyone knows that’s where the shizz goes down.

“”Loose Change””

This movie looks at the events surrounding Sept. 11 and makes the case that the American people haven’t been told the “”whole story.”” The whole story really is, duh. 7 p.m. to 9:30 p.m. Free. Aerospace and Mechanical Engineering building, Room S202

“”Ravi Shankar’s Festival of India II””

This famous sitarist and composer from India will perform a special show filled with pretty colors and lots of vegetarian food. Well, we should hope so. 7:30 p.m. $25 to $42. Centennial Hall

Old Time Relijun

This band’s Web site said it sounds like “”primitive swamp stomp ‘n swagger meets gutsy fucked-up free jazz and throat-singing punk gospel.”” I didn’t think I could describe it any better than that. With Golden Boots and Dawn & Kee. 9 p.m. $6. Solar Culture, 31 E. Toole Ave.

“”Tuesdays With Morrie””

The Arizona Theatre Company is doing an adaptation of the bestselling book. The whole thing is about a young guy visiting his old college professor once a week to talk about life and philosophy. It sounds kind of like “”Apt Pupil”” or something, except without the Holocaust references and murdering of bums. 2 p.m. $26 to $44. Temple of Music and Art, 330 S. Scott Ave.

TV on the Radio

This politically charged indie rock band mixes African tribal rhythms, jazz and slashing guitar rock to create a powerful and gripping performance. It’s also playing with a band called Celebration, whose lead singer looks like Karen O. (Finally, the reason you should come) 9 p.m. $12. Club Congress, 311 E. Congress St. (21+)

UA Poetry Center presents the Persona reading

If you didn’t want to pay $10 at the bookstore to purchase a copy of this student literary magazine, you can see students read their stuff for free. Ah muse, being cheap is so inspiring. I think I shall write a calendar. 8 p.m. to 9:30 p.m. Free. Modern Languages building, Auditorium
