The Janoskians specialize in both pop punk mischief and pandemonium with their own style of “social disturbance”. In February 2014, that pandemonium erupted like never before in Times Square when 20,000 fans showed up along with Republic Records—who signed the boys in the aftermath. That summer, they cooked up their hit song “Real Girls Eat Cake” and partnered with LIONSGATE® for a feature length film that is due out in 2015. In August 2014 they launched a global invasion with the “Got Cake Tour”, spanning Europe, North America, and beyond. In 2011, they became one of the most talked-about phenomena on YouTube after uploading a hysterical video entitled “Awkward Train Situations”. Regularly capturing their shenanigans and uploading them to the site, the Australian-born and Los Angeles-based five-some soon garnered 2 million-plus subscribers and over 200 million views. They hit the States for 2013’s “#NotaBoyBand” tour, selling out every date of the tour in advance. Along the way, they shut down notable locations worldwide, attracting thousands of screaming girls to London’s Hyde Park and the Beverly Center in Los Angeles.d".

When two distinct personalities join together for a singular musical mission, something special happens. Bay area twosome Kalin and Mylesstir up pop, hip-hop, and R&B into an irresistible and inimitable hybrid affectionately and appropriately dubbed "Hip Pop".

Even though they reflect a time-honored tradition, the boys represent the future from the inception of their music to their style. First meeting at a local movie theater in 2011, they kept in touch on Facebook and began formally making music together, creating their own beats, singing, and rapping. Soon afterwards, they dropped "More Than Friends" online, and the response was instantly overwhelming. They performed shows with the likes of Austin Mahone and Megan & Liz and slowly developed a fervent fan base. Headline gigs then followed and started selling out everywhere across the country.
