 This has led to a resurgence of popularity for more traditional progressive metal bands like Dream Theater and Symphony X, and also has led to the inclusion within the progressive niche of bands that do not necessarily play in its traditional style such as thrash/power Nevermore and technical death metal pioneers Necrophagist and Obscura.These bands are often labeled progressive being as they play complex and technical music which do not readily cleave to any other genre.In the late 2000s, bands such as Born of Osiris, Periphery, Tesseract, Animals as Leaders and Vildhjarta popularized the "djent" style of progressive metal in a sound originally developed by Meshuggah.
