Sci-Fi Crimes is the fifth studio album by American rock band Chevelle, released on August 31, 2009 through Epic Records.

[3] On April 9, 2009, Chevelle debuted two new songs, "Letter from a Thief" and "Sleep Apnea" at a concert in Atlanta, Georgia.

Unlike previous albums, Sci-Fi Crimes was recorded live in the studio as a band, without the use of samples.

[1] Jared Johnson of Allmusic says "This is most certainly the same band that draws frequent comparisons to Tool, with its crunchy guitar attack and Loeffler's unforgettable vocal delivery.

But it's their ability to pull off such flippant tales with their characteristic punch that gives Sci-Fi Crimes a humanizing appeal not found on their previous records.

6 on the US Billboard 200 with sales of about 46,000, the highest entry on the chart for the band, before being surpassed by their seventh studio album La Gárgola in 2014.
