Tony Bennett and Lady Gaga will be here April 23 for what promises to be an unforgettable evening celebrating their recently released collaborative jazz album, "Cheek to Cheek." The unlikely duo spans 60 years in age, but their chemistry brought new life to classic jazz standards such as "It Don’t Mean A Thing (If It Ain’t Got That Swing)" and "I Can’t Give You Anything But Love."

At 88, Bennett remains the oldest artist in history to have an album top the Billboard charts, while "Cheek to Cheek" became Lady Gaga’s third consecutive chart-topping album in just over three years. ACL Live’s 2,750-person audience will be just a fraction of Lady Gaga’s usual crowd. To be one of the few, buy tickets starting at 10 a.m. Friday.

He’s not yet a legend, but Hozier is having a major breakout moment. His debut single "Take Me To Church" appeared on his 2013 EP but gained traction once the video for the powerful blues track went viral this year. The song is unavoidable these days, and it’s been nominated for song of the year at the Grammys. According to his website, the Irish singer-songwriter has sold out his next 40 shows across six countries. He’ll play Austin Music Hall on April 21, and tickets for the show go on sale at 10 a.m. Friday.
