Context: Le Tigre ( ) is an American electroclash band from the United States, formed by Kathleen Hanna (formerly of Bikini Kill) and Johanna Fateman in 1998 in New York City.

Seth Bogart is the second overall solo studio album written, recorded and performed by Hunx and His Punx vocalist Seth Bogart.  It is the first studio album to be released under his name, as his previous solo record "Hairdresser" was issued under his stage name Hunx.  Bogart had enjoyed making music as his Hunx character, but had wanted for a long time to start recording material that showed more of his true self, "like a weird teenager’s version of an adult album" as he said in an interview.  Therefore, he decide to take more than two years to make the album, unlike during his Hunx period where he would make a record in five days or less.  "Seth Bogart" was produced and co-written by Cole MGN, and also features vocal performances from Chela, Kathleen Hanna, Tavi Gevinson, Jeremiah Nadya and Clementine Creevy.
