The technical death metal band Allegaeon from Fort Collins, CO, is constantly evolving. Their seventh album "The Ossuary Lens" marks the return of original vocalist Ezra Haynes, who left the band in 2015 after "Elements of the Infinite". While the last few albums experimented with clean vocals, Haynes' return brings back the harsh, brutal sound. Technically sophisticated and lyrically scientific, Allegaeon remains true to their style - a blend that Haynes describes as "melotech" (melodic, technical death metal).
