Given the following context:  The Smashing Pumpkins' distinctive sound up until Adore involved layering numerous guitar tracks onto a song during the recording process, a tactic that Mellon Collie and the Infinite Sadness coproducer Flood called the "Pumpkin guitar overdub army." Although there were a lot of overdubbed parts on Gish, Corgan began to really explore the possibilities of overdubbing with Siamese Dream; Corgan has stated that "Soma" alone contains up to 40 overdubbed guitar parts. While Corgan knew many of the songs would be difficult or impossible to replicate from their recorded versions in concert (in fact, some songs were drastically altered for live performance), he has explained the use of overdubbing by posing the question "When you are faced with making a permanent recorded representation of a song, why not endow it with the grandest possible vision?" This use of multilayered sounds was inspired by Corgan's love of 1970s popular artists & bands such as: David Bowie, Cheap Trick, Queen, Boston, and the Electric Light Orchestra, as well as shoegaze, a British alternative rock style of the late 1980s and early 1990s that relied on swirling layers of guitar noise for effect. Mellon Collie coproducer Alan Moulder was originally hired to mix Siamese Dream because Corgan was a fan of his work producing shoegaze bands such as My Bloody Valentine, Ride, and Slowdive.Like many contemporary alternative bands, the Smashing Pumpkins utilized shifts in song dynamics, going from quiet to loud and vice versa. Hüsker Dü's seminal album Zen Arcade demonstrated to the band how they could place gentler material against more aggressive fare, and Corgan made such shifts in dynamics central to the pursuit of his grand musical ambitions. Corgan said he liked the idea of creating his own alternative universe through sound that essentially tells the listener, "Welcome to Pumpkin Land, this is what it sounds like on Planet Pumpkin." This emphasis on atmosphere carried through to Adore (described as "arcane night music" in prerelease promotion)...  answer the following question:  Whose album did Flood co-produce?
The answer to this question is:
The Smashing Pumpkins
