Casting Crowns' Mark Hall (lead singer) states that when he was a teenager, he heard a song being played with just a keyboard in the background. He liked that it sounded as if the singer was right there with him in that room. This is where "The Acoustic Sessions: Volume One" was born.
The Acoustic Sessions: Volume One received mostly positive reviews from music critics. About.com's Kim Jones gave the album a four out of five stars, affirmed that "Casting Crowns totally hit the nail on the head with Acoustic Sessions: Volume 1." James Christopher Monger of Allmusic gave the album three out of five stars, commenting how it "kicks the concept up a notch" from what they do on tour.Christian Broadcasting Network's Chris Carpenter gave the album four-stars-out-of-five, and highlighted that "The Acoustic Sessions: Volume One is a must-have for all avid Casting Crowns fans. For those who aren’t, it is still a good pick-up for all the incredibly rich, worshipful lyics that are brought to the forefront by the simplicity of strings and a prayer." Grace S. Aspinwall of CCM Magazine gave the album three-stars-out-of-five, surmising that the acoustic album "capture[s] the essence of who they are," especially them in concert. Laura Chambers of Christian Music Review rated the album a four-and-a-half-points-out-of-five, and -and noted that "Diehard fans of Casting Crowns will want to check out this disc. Those who don’t care for the band and think every song sounds exactly the same may be surprised by it." Christian Music Zine's Joshua Andre gave the album a 4.25 out of five stars, calling it a "Well done" effort. Jonathan Andre of Indie Vision Music gave the album a three out of five stars, highlighted that "The result is a mixed bag of acoustic songs that are a certain purchase if you enjoy their previous work- with some songs performing one better than the original, yet other songs seemingly tired and out of place on an album that many may question the track order or even the tracks themselves." Jesus Freak Hideout's Roger Gelwicks gave the album three out of five stars, noting how it "stands out from their catalog: it shows Mark Hall and friends trying new things and stretching themselves creatively. Even if the songwriting itself hasn't improved (and to be sure, the lighter instrumentation doesn't fix the hackneyed lyrical choices throughout), the lighter side of Casting Crowns is a pleasant change from their norm...by no means a masterpiece, but at this rate, listeners should gladly welcome Volume Two when it comes around." Jono Davies of Louder Than the Music gave it four-and-a-half out of five stars, praising how "With Casting Crowns, although they have some great songs, I always think musically they could do a bit more on their studio albums. But for me, this is the best Casting Crowns album so far. The songs are solid and then musically they are much more creative in this stripped down style. I think Casting Crowns have surpassed themselves and also given a new lease of life to some older tracks." Kevin Davis of New Release Tuesday gave it a four-and-a-half out of five stars, evoking how the album is "filled with songs that both challenge and encourage believers in their walk".
