The Carnival of Madness tour is going strong, as audiences across the country get to take in tour originators Shinedown and their cohorts. This Readers Poll reflects on the history of the successful trek and asks you which of the bills has been your favorite.

The Carnival of Madness launched in 2010 with Shinedown fronting the festivities. They welcomed Chevelle, Puddle of Mudd, Sevendust and 10 Years for the trek, which helped establish the brand for years to come. In 2011, with Shinedown otherwise engaged, Theory of a Deadman took the headlining spot, supported by Alter Bridge, Black Stone Cherry, Adelitas Way and Emphatic for a hard rocking run through North America.

In 2012, the ladies invaded the male-dominated trek as headliners Evanescence and support act Halestorm were joined by Chevelle, Cavo and New Medicine. And in 2013 it's all come full circle with Shinedown supporting their most recent record and headlining once again. They're joined by Papa Roach, Skillet, In This Moment and We As Human.

That's four years worth of great music that has established Carnival of Madness as one of the premiere hard rock events. Check out the Readers Poll below and vote for your favorite Carnival of Madness lineup.
