Those lucky enough to have discovered Explosions in the Sky at some point over the last 12 years know what to expect when the band puts out a new album.

The instrumental quartet’s signature sound is unmistakeable; the elaborate, brilliantly-layered guitar parts and pounding rhythms create an enveloping experience like no other. They make emotionally-expressive music without words.

The Austin, Texas-based group’s latest installment, “Take Care, Take Care, Take Care,” is another sonic roller-coaster ride through the land of introspection and nonverbal storytelling. Like every Explosions CD to date, the tracks take the listener on a wandering journey.  Several songs feature the group’s trademark five-minute crescendo, starting out with little more than an electric buzz and winding up with a sound so full one might not believe it is not coming from an orchestra.

Overall, though, the band’s sound has clearly evolved. Even just since their last release, 2007’s “All of a Sudden I Miss Everyone,” it has become much more layered and complex. The historically simple lineup of three guitars and a drum set is beefed up with a lot more production.

“Last Known Surroundings,” Take Care’s first song, sets the tone well for the whole album.  After a few seconds of a feedback, the first hint of studio-produced percussion makes it obvious there is more going on than ever before. This may be a totally new experience for the seasoned Explosions fan, but fear not.  They do not overdo it, and it adds a welcome new weapon to their repertoire.

In fact, the track with perhaps the most production work, “Be Comfortable, Creature,” is one of the best on the album. The distortion and faint clicking percussion sound will be familiar to fans of Radiohead, and they complement this beautiful tune perfectly.

Memorable guitar lines are a big part of an Explosions album, and the ones here will have you whistling for days.  Perhaps the catchiest of all can be found on the album’s penultimate song, “Postcard from 1952.”  This rolling epic of a piece is perhaps the highlight of the album.

Complacency is always a threat when a band finds a formula that works. What Take Care shows is that the band is able to develop its sound without losing its extravagant simplicity which has earned it a huge cult following and considerable critical acclaim. Loyal fans who have not picked up this album yet should do so immediately. To those who maybe have heard good things but still are unfamiliar with Explosions: This is as good a place as any to start.
