Screaming Bloody Murder is the fifth studio album by Canadian rock band Sum 41, released on March 29, 2011, after many delays.

[6] Even though new guitarist Tom Thacker was already a part of the band and co-wrote the title track of the album, all guitars were still recorded by singer Deryck Whibley.

It was announced that a new song entitled "Skumfuk" was set to appear on the Warped Tour sampler CD, though it eventually wasn't ready for release in time.

The song began rising in popularity online, which led Sum 41 to start playing it live on their European tour in October.

It was later revealed on the back of the album that "A Dark Road Out of Hell" was indeed true, comprising tracks 7–9 entitled "Holy Image of Lies", "Sick of Everyone", and "Happiness Machine".

[7] On January 8, 2011, it was announced that the band would release the radio single "Screaming Bloody Murder" on February 7, 2011, in the United States.

[15] In July 2011, Matt Whibley confirmed that the music video for the first single "Screaming Bloody Murder" would be left unreleased due to its content and difficulties with the label.

[17] On February 29, 2012, the band shot a music video for "Blood in My Eyes", with director Michael Maxxis in Los Angeles, California.

[24] The band performed the song live for the first time on February 4, 2011, in Paris, France, the first date of their first official European leg of the Screaming Bloody Murder Tour.

"Baby You Don't Wanna Know", along with "Time for You to Go", was one of the two songs that were written and recorded by the band at the last minute, on April 7, 2010, at EastWest Studios in Hollywood, California.

Jonah Bayer of Alternative Press said: "While we believe Sum 41 has the potential to succeed without the power chords, the fact that only a handful of musical ideas are fully developed in the album is a frustrating experience to listen".

"[34] Grace Duffy of Under the Gun said: Screaming Bloody Murder takes things up a notch, with a forceful and cutting rhythm and vocals to match.

[37]Sum 41 was nominated for the 2011 Grammy Award for Best Hard Rock/Metal Performance for the song "Blood in My Eyes", but they lost to Foo Fighters.
