Harmonix has also been in contact with major music labels who previously have been requesting Harmonix to include their music to participate in creating songs with the Network. One label, Sub Pop, has revealed they will plan to release all songs and albums on their label to the "Rock Band" Network, including early music by Nirvana, Mudhoney, Sleater-Kinney, The Postal Service and The Shins, though the amount and rate of content will be affected by the difficulty of the tools Harmonix will provide to make the music tracks. For the service's launch, the label prepared 25 songs through the various authoring companies. Tony Kiewel of Sub Pop stated that they see the "Rock Band" Network as another music distribution path alongside vinyl and CD and plan to release future songs from their label on the Network alongside traditional music media. One such band includes Flight of the Conchords, who announced that three of their songs, including two from their first album, would be coming to "Rock Band" at the 61st Primetime Emmy Awards, later clarified by Sub Pop that they would be Network tracks. Label Side One Dummy announced that they will be releasing The '59 Sound and Old White Lincoln, the two first singles from The Gaslight Anthem's The '59 Sound album in early March 2010. On April 30, 2010, Rhythm Authors announced that they were partnered with Sumerian Records to bring the label's music to the "Rock Band" Network; so far Asking Alexandria, Veil of Maya and After the Burial are confirmed to be in production.
