The Black Keys released their new album, “El Camino,” on Tuesday, Dec. 6, marking the release of their seventh album since the band’s inception in 2001.

The blues-rock duo consists of Akron, Ohio natives Patrick Carney and Dan Auerbach, and is best known for the songs “Girl Is On My Mind,” “Tighten Up” and “Howlin’ For You.” Carney and Auerbach claimed three Grammys for their previous album “Brothers.”

The duo promoted “El Camino” in a unique way. According to Pitchfork Media, Carney and Auerbach ran fake advertisements in the Akron Beacon Journal encouraging interested parties to call the band about a 1994 Chevy El Camino for sale.

Ironically, a Chevy El Camino is not on the album cover; instead, the album cover displays a Chrysler Town & Country. Ironically, a Chrysler Town & Country–not a Chevy El Camino–is displayed on the “El Camino” album cover.

For this album, the men of The Black Keys worked with producer Danger Mouse, who has previously produced their album “Attack and Release,” their single “Tighten Up” and has worked with U2, Beck and Gnarles Barkley, among others.

In an interview with Spin, the duo said they drew inspiration for their latest album from the Clash, the Cramps, old rock n’ roll, rockabilly and garage-rock records.

“El Camino” opens with the lead single track “Lonely Boy,” featuring a hard-hitting blues riff with a fuzzed-out bass and a keyboard and drum accompaniment that screams of “a love that keeps me waiting.”

The 11-track album has an interesting variety of songs throughout, with a mix of Texas blues, Chicago blues, Delta blues and boogie-woogie, and samples different selections while maintaining the fuzzed-out, bordering psychedelic guitar riffs that the duo developed during their previous three albums, but perfected with “Brothers.”

As such, “El Camino” is a departure from The Black Keys’ first album, “The Big Come Up,” which was a pure Blues album, and relied on traditional Blues numbers. However, the group has developed its sound from “Brothers” into a more hard-hitting, fuzzed-out sound that could be compared to a mix of ZZ Top and The Clash.

The album has a psychedelic sound, evidenced by the songs “Sister” and “Gold on The Ceiling,” and has a few songs that remind long-time listeners of the bluesy sound that initially made the duo well-known, including “Run Right Back.”

One of the unique selections on the album is a song called “Little Black Submarine.” This song starts off as slow, shuffle blues, sung softly by Auerbach, until just after the two-minute mark, transitioning into hard blues rock reminiscent of early Led Zeppelin and Jimi Hendrix. The song speaks about lost love and having a broken heart.

“El Camino” has more of an edge than The Black Keys’ previous work. The album contains more hard-driving and faster guitar riffs, and demonstrates the influence of the early hard rock n’ roll groups. More than likely due to Danger Mouse’s hand in the production, this album is much tighter than “Brothers.”

“El Camino” is great for long-time listeners because it shows the evolution of the groups’ sound since its early days. New listeners are given a fresh blend of blues, rock and funk that is unique to  The Black Keys.
