It was the band's first major label release, though Warner Bros. had lobbied to release Flip Your Wig until the band decided to let SST Records have it. Candy Apple Grey also marks the completion of the band's transition from hardcore punk to a more well-rounded sonic style which would later come to be known as alternative rock. As usual, Bob Mould and Grant Hart individually wrote tracks on the album. While the band's earlier, more frenetic style is still evident, Candy Apple Grey also features more introverted, toned-down material, including a relatively large amount of acoustic guitar.
The singles released from this album were "Sorry Somehow" and "Don't Want to Know If You Are Lonely", both written and sung by Hart. The latter was accompanied by a promotional video which earned airtime on MTV. Candy Apple Grey was the first Hüsker Dü album to chart on the Billboard Top 200, but despite receiving exposure on radio as well as MTV, it peaked at No. 140.
