The weather's cooling off, but the number of shows is heating up as we head into the back half of September. Let's look at this week's highlights.

Famed soul diva Diana Ross hits EnergySolutions Arena for a concert featuring a string section and horns that will almost certainly feature many of the 67-year-old living legends Motown classics. Ross is not the most prolific touring artist out there, and this show offers a relatively rare chance to see songs like "Ain't No Mountain High Enough," "Stop! In the Name of Love," live. Tickets start at $40 for the 7:30 p.m. show. Here's one of Diana's disco hits, "Upside Down."

An interesting gig arrives at The State Room on Tuesday night when former Men At Work frontman Colin Hay rolls in behind his latest solo album, "Gathering Mercury."

Also Tuesday night, reggae fans will want to head for The Complex for the Second Annual Sunsplash Concert featuring New Zealand's Katchafire. Tickets are $20 in advance for the 7 p.m. event.

Here's Katchafire playing "Seriously."

Also, the Mary Poppins show at The Capitol Theatre continues this week with a 7:30 p.m. show Wednesday night.

And don't forget that at 6 p.m. Wednesday you can catch The Wood Brothers during a 30 minute free in-store performance at the University Graywhale on 208 S. 1300 East. They'll be at The State Room on Thursday night for a full-length show. I'll have much more on that show later this week.
