The phrase ‘pop-punk’ might leave a negative connotation in people’s heads, reminding them of Vans Warped Tour bands whose time has come and gone. But Diet Cig marries fast-and-furious pop-punk power chords with simple and relatable lyricism brimming with confidence and subject matter that Blink-182 wouldn’t want to touch, like wanting to eat ice cream on your birthday. The duo of singer/guitarist Alex Luciano and drummer Noah Bowman have sold out shows all over the country, including their stop at Rock and Roll Hotel. With this tour, though, the effervescent duo became a quartet by adding Spook School bassist AC Cory and keyboardist Karli Helm. But still, it was Luciano and Bowman that stole the show as they have time and again.
