Context_4 : Warehouse: Songs and Stories (1987) is the sixth and final studio album by alternative rock band Husker Du, originally released by Warner Bros. Records as a double album on two vinyl LPs. The band dissolved following the tour in support of its release, in part due to disagreements between songwriters Bob Mould and Grant Hart over the latter's drug use. This album, along with "Candy Apple Grey", showcases the increasing maturity of Mould and Hart's writinga change which alienated some long-time fans. This album is also known for its battle between the two songwriters, with Mould famously telling Hart that he would never have more than half of the songs on a Husker Du album.

In addition, Phillips, Dinning, and Guss wrote and recorded an entirely new song titled "Eyes Open Wide," without the participation of Nichols, who felt some of the remaining unrecorded studio outtakes the band had would be better to release than a new song. Rob Taylor, who at the time was the lead guitar player in the band Lapdog, with Nichols and Dinning, is credited as playing "additional guitar" on the track.
