American rock band Mayday Parade made their debut in the mid-aughts with the gold-certified A Lesson in Romantics, which featured a passionate emo-punk sound similar to contemporaries like Yellowcard, Plain White T's, and All Time Low. Into the 2010s, they incorporated a harder rock edge that fleshed out their punchy roots on releases like the Top 10 Monsters in the Closet (2013) and Black Lines (2015).a
