Today on the 3@3, RedEye Chicago Columnist Ernest Wilkins and Chicago Tribune Reporter Nina Metz talk with host Steve Edwards about the topics and themes of the day.

Which include:

Steve Edwards: Today is tax day and that means events, protests and political posturing dominate the headlines. But what does tax day mean to you, and are you getting any money back this year?

Nina Metz: Concussions in sport is not a new headline, but the rate in which grown men are bloodying themselves during the NHL playoffs is startling. Do hockey fights help or hurt the game? And is it only done in the name of the fan?

Ernest Wilkins: Tupac made a comeback this past weekend at Coachella. Well, his hologram did. Now, there are plans to take the futuristic technology on tour. Did we just see the future of live music?
