Wish Upon a Blackstar is the second vocal studio album (third overall) from the American electronic rock project Celldweller.

Klayton began to work on the album in 2004,[2][3] and it was originally slated for release in 2006, though it was ultimately delayed numerous times.

I can tell you that I am thinking about alternative methods of releasing this album altogether, but I won't say anything until I'm ready to commit... that always gets me in trouble".

[7]On March 9, 2009, Klayton announced that the album would be titled Wish Upon a Blackstar,[8] and he revealed the track listing on April 20, 2009.

I just don't totally feel right about releasing one song at a time for this album, but I have no intentions of waiting 'til I'm done with the whole thing either.

[11]The first four chapters were released as digital downloads only, and they were available in two editions: Originally, there were to be ten songs on the album, but Klayton added seven more to the final CD, namely "Birthright", "The Seven Sisters", "Memories of a Girl I Haven't Met", "It Makes No Difference Who We Are", "The Arrival", and "The Departure" (Deluxe Edition only).

Graphic artist Sam Hayles, who had previously designed the artwork of Soundtrack for the Voices in My Head Vol.

[13] Also, Klayton asked Celldweller fans to suggest ASCII-based emoticons to represent each song on the CD artwork.

[21] He later confirmed that BT would be remixing the songs "Louder Than Words" and, Toksin would work on "So Long Sentiment", and J. Scott G. and Joman on "The Best It's Gonna Get", with Imprintz & Kloe.

[22] As of mid-2012, only Toksin's remix of "So Long Sentiment" had been released, first on the deluxe edition of Chapter 02 of Wish Upon a Blackstar, then on The Complete Cellout Vol.

American author Josh Viola wrote a science-fiction novel based on the album, titled Blackstar.

On July 13, he posted a video from his iPhone, showing the synth bridge from an unreleased demo of "Louder Than Words", though the segment did not make it to the final cut of the song.

[24] On May 24, 2010, Klayton released a sample take of "The Lucky One" on his website, allowing fans to submit their vocals as part of a contest to be featured on the album.

[1] On April 30, Klayton announced a Deluxe Limited Edition, with a continuous mix and a "different sequence from main album release, with custom transitions & all".

Miranda Yardley from Terrorizer stated that: "You cannot begin to accuse Celldweller of being a one-trick pony and on the other hand, each track is distinctly their work.

"[48] Gregory Burkart from Fearnet praised the album, stating that "Wish Upon a Blackstar is an impressive example of Celldweller's evolutionary skills – adopting, adapting and rising above the genres that play a part in it.

[47] In a less positive review, Fred Thomas from Allmusic said that, "While the heavy production sounds by turns crisp or brutalizing, even the most exciting moments can't save the album from its cheesy lyrics and played-out musical choices, which are as abundant as its moments of legitimate excitement.

"[7] Klayton has stated that many of these songs that did not end up on the album proper will make up the bulk of a second official Beta Cessions collection: "In fact The Beta Cessions II (when I ever get around to working on those tracks) will be primarily new material and not a bunch of remixes and alternative versions of songs from the sophomore Celldweller album".

[50][51] Two singles issued in anticipation of Wish Upon a Blackstar, "Shapeshifter" and "Tragedy", did not appear on the album[52] and also ended up on the Celldweller re-issue.

[54] On October 26, 2011, it was announced that a demo of "IRIA" would be issued if the Groupees Halloween Trick or Treat charity event earned over $5,000.

[57] On November 14, at the end of the campaign, donors unlocked a new three-song EP, Groupees Charity Fundraiser, with demo tracks that were intended for Wish Upon a Blackstar.

[3] The demo songs released during the Groupees promotions were to be re-released on the second disc of the 2-CD Deluxe Edition of the Celldweller Debut Album 10th-Anniversary Re-Issue.
