Incesticide, as I'm sure you all know, is not a formal album; it is a collection of b-sides, rarities and unreleased songs, recorded between 1988 and 1991. This was released only 9 months before In Utero, and was basically used to hold off fans until the 3rd Nirvana album; In a sense, this took on an identity of it's own as Nirvana's 3rd album.
The first song, Dive, is follows the tradition of strong introductory tracks on Nirvana albums; equal parts Cheap Trick and Black Sabbath, the song is their hit song "In Bloom"s Darker, angrier, twin brother. The slinky bass line is among Krist Novoselic's best.
The second song, Sliver, is among the bands best tracks. A spikey burst of cathartic pop punk, this song was the only charting hit on Incesticide, reaching 19 on the Modern Rock charts. Although it deals with themes of alienation, it is among Nirvana's most bouncy tracks, owing much to Kurt's love of The Pixies, and The Vaselines.
The album isn't all classics though; tracks like the terrible, teenage garage band throw away "Stain", the subpar sludge of "Big Long Now", and the self-parodizing "(New Wave) Polly" remind you that this album is just a b-sides collection; still gems like "Dive", "Sliver", "Been A Son", "Son Of A Gun", "Aero Zeppelin", and "Aneurysm" prove it's a b-side collection worth owning, for sure.
