Happy Mother's Day Weekend! If perhaps you're looking to take mom out to a good concert this weekend, there are a few choices. Ariana Grande performs on Saturday night at T-Mobile Arena at 8pm. Tickets run from $35-$250. (We know that not all the moms out there are over the proverbial hill!) Also performing tonight is Pitbull, who will get everyone on their feet at Zappos Theater at Planet Hollywood at 9pm. Tickets are $40-$150. Pitbull also performs this coming Wednesday night. All the moms I know love to get their groove on to Pitbull! If mom is a bit older and loves her oldies, Gary Puckett & the Union Gap are at the Showroom at the Southpoint tonight and Sunday night at 7:30pm. This is the bargain show of the weekend as tickets are only $30-$40. Later in the week, Santana returns to the House of Blues at Mandalay Bay to continue his mini residency. Tickets are $90-$350 and Santana will have shows through May 25.
