A greatest hits collection, the CD came out in 2002 and this two record vinyl version came out in 2015. These are songs most everyone knows who listens to Rock music. The first song “You Know You’re Right was the last song Nirvana recorded and was never released. There is also a remix of “Pennyroyal Tea” by Scott Litt intended for a single but dropped after Kurts death. “Silver” is a non album single from 1990. Two earlier songs are from 1989. There are four from Nevermind,three from In Utero and two from Unplugged. The record comes with an inset with liner notes by David Fricke. The record plays at 45 rpm and sounds really good.
