All Days Are Nights: Songs for Lulu is the sixth studio album by Canadian-American singer-songwriter Rufus Wainwright, first released in Canada through Decca Records on March 23, 2010.

Images used for the album insert and other promotional material were taken during a photo shoot with photographer Kevin Westenberg on January 5, 2010, at Park Avenue Armory in New York City.

[11][12] Celebrities in attendance included Eva Amurri, Penn Badgley, Drew Barrymore, Alexis Bledel, Alan Cumming, Scarlett Johansson, Michael Kors, Lucy Liu, Natasha Lyonne, Kyle Martino, Lou Reed, Susan Sarandon, Christian Siriano, Amber Tamblyn, and Zachary Quinto.

[5] References to New York City in the song's lyrics include Grand Central Terminal, Madison Square Garden and the Empire State Building.

[13] "Les feux d'artifice t'appellent" is the closing aria from Wainwright's debut opera, Prima Donna, which premiered at the Manchester International Festival in July 2009.

[13][18] On the album, Wainwright taps on the piano's sounding board and runs his hands along its strings to simulate the "crackle and cascade" of fireworks (which light up the Paris skyline in the opera).

[20][21] The Edmonton Journal's Sandra Sperounes described the song as a reenactment of Wainwright's "plodding" steps, which steadily build into a "promise of triumph or, at the very least, temporary relief from pain".

[20][23] The production premiered in Berlin in April 2009, and contained 24 sonnets, each stylized with cross-dressing actors, "lavish costumes, huge hair-dos and [Wilson's] trademark lighting and puppet-like choreography.

[7] However, concerts did include an accompanying film by Scottish video artist Douglas Gordon and some "glam-ish costuming" by fashion designer Zaldy Goco, who created a 17-foot-long, black feathered cape for Wainwright.

[1][5] Regarding his tour and ability to face his grief over his mother's death, Wainwright admitted: "This is such new territory for me and there are moments when I think I'm doing fine and two seconds later I'm on the floorboards so it's uncharted.

[29] The song cycle was also sung by soprano Janis Kelly and mezzo-soprano Angelika Kirchschlager during concerts with Wainwright on March 9, 2014, in Sankt Pölten, Austria[30] and June 14, 2015, in Ludwigsburg, Germany.

Though Sperounes praised Wainwright for his ambitions, she criticized him for "dwell[ing] on his misery as most of his songs slowly plod along, with only a brief flurry of notes to punctuate the occasional phrase, as if he's mustering up the strength to make it through another minefield.

"[22] After asserting that "darkness" is a central theme to the album, music critic T'Cha Dunlevy wrote that the lack of lush orchestrations and arrangements Wainwright is known for emphasized his solitude, "exposing him in ways we haven't heard before.

"[1] A reviewer for BBC claimed the album is successfully intimate and intense, and suggested it would be appropriate for "either a wet afternoon or long candlelit nights of soul searching".
