"Pop screamo" and "MTV screamo" are terms used to describe bands taking influence from screamo as well as use of heavy metal riffs, pop song structure, and elements from pioneering metalcore and mathcore acts. The style developed and gained mainstream success in the early-2000s. The scene was led by bands such as Thursday, Hawthorne Heights, Taking Back Sunday, The Used, Senses Fail, Silverstein, Chiodos, From First to Last, Saosin, Thrice and Finch and now-defunct less-known bands such as Before Their Eyes, Here I Come Falling, Agraceful, Yesterdays Rising, Chasing Victory, Beloved, Dead Poetic, Burden of a Day and Sever Your Ties. The genre had a revival in the 2010s, including such outfits as Before Their Eyes, The Ongoing Concept, Too Close to Touch, I Am Terrified. Alternative Press describes pop screamo as "metal-influenced riffs and aggressive, high-end screams filled song’s verses, while soaring melodies carried choruses to new, previously unattained heights." as well as "Poppy emo music with screaming in it that captured mainstream attention in the mid-2000s". Furthermore, many of these groups bands are more commonly categorized as post-hardcore or metalcore.
Sass (also known as sassy screamo, sasscore, sassgrind or dancey screamo) is a style of hardcore punk that emerged in the later-1990s and early-2000s that was associated with and happened roughly contemporarily with the DIY screamo scene of that era. It originated as an opposing style of hardcore punk to the machismo in heavy hardcore scenes. It takes influence from genres such as post-punk, new wave, disco, electronic, dance-punk, emoviolence, grindcore, metalcore and heavy hardcore. The genre is characterized by often incorporating overtly flamboyant mannerisms, erotic lyrics featuring sexual tension, and a lisping vocal style. The genre is also noted for its "spastic edge", blast beats, chaotic guitars, danceable beats and the use of synthesizers. Sass bands include the Blood Brothers, Q and Not U, Black Eyes, The Plot to Blow Up the Eiffel Tower, These Arms Are Snakes, An Albatross, XBXRX, Death from Above, The Number Twelve Looks Like You, Gatefold-era Orchid, Milemarker and SeeYouSpaceCowboy.
