In June 2012 they launched their single "Sort out You Life Jamaica", commemorating 50 years of Jamaican independence.
The group have performed at several of Jamaica's major festivals, including Rebel Salute, Reggae Sumfest and The National Grand Gala. In an April 2013 Rolling Stone magazine article Chris Blackwell, founder of Island Records, stated "There's a band called the No-Maddz who are more like theater than a group. They're actors. It's this whole audio-visual kind of thing. It's different. But they're really good, really talented and really smart."
In Summer 2013, they launched the production Breadfruit is the New Bread, Baby, a theatrical expression of the No-Maddz "Bongo Music" that ran for five nights per week for two months; It was later selected by the government as an official representation of Jamaica's performing arts and new popular culture at Carifesta XI in South America.
The Trod Live series was revamped for the re-opening of the historic CountrySide Club in Kingston. The special series saw the band playing every last Saturday for four months.
In 2014, No-Maddz teamed up with producers Sly and Robbie to record their first studio album entitled Sly and Robbie presents No-Maddz. The album was released on January 27th, 2015. Saxon Baird of MTV Iggy described the album as "a first-rate debut from a band that seems poised to offer great things to come."  In a review, Eric Magni of United Reggae wrote that it the album was "a joy from start to finish."
In April 2015 In The Morning Yah, a book of Shepherd's poetry, was published.
