At the age of 14, comedian Aries Spears found his calling. It wasn’t long before Spears was a principal member of the hit sketch show MADTV — not only as a performer, but a writer as well. He recorded his 2-disc comedy album, I Ain’t Scared, at the famous Icehouse in Pasadena. He has performed on Def Comedy Jam on HBO and Showtime At the Apollo. In addition to his credits as a comedian, Aries has made appearances in several movies. After being spotted in a comedy club, he was given a role in Home of Angels. From there he has been in Why Do Fools Fall in Love and Jerry Maguire. Spears has also made appearances on talk shows such as Loveline, Vibe and Soul Train. He plays a good range of characters and does a variety of different voices, too. His experience on sketch shows and TV gives him an advantage over other comics. Tonight’s show at the Improv starts at 7:30 and performances continue through Sunday. Tickets are $25. (Kali Fencl)
