Improvised Electronic Device is the fourteenth full-length studio album by Vancouver industrial band Front Line Assembly, released in 2010.

Guitarist Jared Slingerland said in a conversation with The Rumpus, "I mean, I.E.D., it's obvious what it is, but because it's still kind of a sensitive issue, Bill came up with the idea of 'electronic device.'

I usually write about more general stuff [...], so it's the first time I wrote such personal lyrics, and I wasn't sure if Front Line was the right place for it, but I figured what the hell, it's my band.

"[7] The song "Angriff" was inspired by the band's visits in Russia[7] and "is peculiar in that the chorus is performed in German", as noted music magazine Side-Line.

[8] Leeb attributed this choice to his Austrian origin: "Actually, since I was born and raised in Vienna, Austria, German was always my first language, it only seemed natural to eventually reclaim my heritage and do a song in my mother tongue.

While it turned out to be the last Front Line Assembly album to feature Chris Peterson, live guitarist Jared Slingerland became permanent member and was fully involved in writing.

"[5] "We had two camps", explained Leeb the band's modus operandi during production of Improvised Electronic Device in an interview with Bloody Disgusting: "Jared and Chris have a studio set up and Jeremy has one too, and I would float around between both, and song ideas would get started, and I always thought I'd have the last say, and I'd come in and come up with the choruses and change things and so forth.

"[9] While Leeb focused "more on song writing and lyrics", the other band members and contributors added to what became "a pretty big stack of electronic components that helped create this.

"[9] Leeb mentioned "our analogs, the mini-Moogs, the Pro 1s and all this stuff" as examples, as well as "virtual programs and synths and effects" and the studio gear of Reely and Marshall.

[13] The line-up for all the tours consisted of all official band members except for Chris Peterson for whose absence Leeb, in a 2010 interview with Release Magazine, cited further commitments as reason.

[15][16] Originally German industrial band Die Krupps were supposed to join Front Line Assembly on the North American leg of the 2011 tour, but failed to do so "due to immigration/visa issues".

[12] VIP passes were offered to be purchased in advance that entitled their holders to attend certain activities like soundcheck and meet and greet with the band as well as receive exclusive tour items.

It was released on the occasion of Front Line Assembly's tour in Europe together with mind.in.a.box in September and October 2010,[26][27] due to "Angriff" having "developed [in]to a club hit.

In light of the band's career spanning decades, critics reflected about how the sound and style of Improvised Electronic Device compare to past releases.

These releases he called "disappointing results", and deemed the band to be "back on track" with Artificial Soldier,[39] seeing Improvised Electronic Device in the vein of its predecessor: "Bill Leeb was able to retain his focus and deliver an album that mixes the modern EBM sound of Artificial Soldier with the solid industrial metal of Hard Wired.

"[39] "It seems that he has finally figured out how to make all of those divergent elements come together and work seamlessly",[39] wrote Spencer, recognizing the musical influences of past albums.

He concluded: "Improvised Electronic Device is the first album since Hard Wired in 1996 that could truly be considered a great Front Line Assembly release, and we can only hope that this is the beginning of a new trend.

"[39] Against the background of different musical influences, Patrik Lindström of Brutal Resonance found the album to be "a very varied experience.
