Angelfish is the 1994 self-titled debut and only studio album released by Scottish alternative rock group Angelfish, fronted by Shirley Manson.
 The "Angelfish" album was born out of necessity when Goodbye Mr. Mackenzie's record distributor MCA expressed interest in recording an album with Manson on lead vocals rather than furthering its commitment to the Mackenzies.
 The Mackenzies' record label boss Gary Kurfirst signed Manson as a solo artist, with the remaining Mackenzies performing as her backing band to circumvent the band's existing deal with MCA.
Not Your Kind of People is the fifth studio album by American-Scottish alternative rock band Garbage.
 It was released on May 11, 2012 through the band's own record label, Stunvolume.
 The album marks the return of the band after a seven-year hiatus that started with previous album "Bleed Like Me".
 Guitarist Duke Erikson said at the launch of the record that "working with Garbage again was very instinctual.
 Like getting on a bicycle...with three other people."
 The band emphasized that they did not want to reinvent themselves, but embrace their sonic identity, reflecting their classic sound whilst updating it for 2012.
 Although Shirley Manson's morose dispositions have a presence on the record, many of the songs share a more optimistic outlook on life, influenced by some of Manson's personal experiences during their hiatus.
