Query: The Greatest CD Ever

Without a doubt, Meantime was a monumental CD that changed the way people think of heavy music. A full out assault on the listener, Meantime uses dropped-D tuning to perfection. Their tight, quick riff patterns in different time signatures have been used by a multitde of 90's metal bands (see Deftones, Pantera, Limp Bizkit, etc.) Every song on this album is amazing. It is one of the few CD's I can listen to constantly. Unfortunately, Helmet never received their due praise from the mainstream, mostly because people couldn't label them. It's not metal, it's not hardcore, it's not alternative. It is a captivating album that will stick with you forever.
