Whether it was the long break from touring or married life for all four members, Kings of Leon’s new album “Mechanical Bull” is noticeably less rambunctious than previous works.

That is to say, there is far less sex, drugs and rock n’ roll in their sound, even though some of these do get their mention lyrically.

The album begins with the catchy single, “Supersoaker.” Similar to 2008’s “Use Somebody,” this track is the album’s obligatory pop song. Although it’s not near as lively as the 2008 single, it will certainly get listeners singing along.

Similarly to 2010’s flop, “Come Around Sundown,” “Mechanical Bull” hugs to the bluesy country feel while relying on the crooning of front man Caleb Followill for the point of interest.

Unlike “Come Around Sundown,” this album delivers on this genre with rhythmic bass lines and uniquely soulful guitar solos. This can be seen in the old style blues tracks, “Rock City” and “Family Tree.”

The country genre shines through in the ending track, “On the Chin.” It’s complete with a steel guitar and references to chain smoking and day drinking – so much for the rumors of the front man attending rehab.

The album is weaker when they fall away from their grungy rock style completely. Tracks like “Beautiful War” and “Comeback Story” feature strong melodies, but sound more suitable for John Mayer than Followill’s raspy voice.

Granted, these songs are well written, but fans hoping for more of the old angst and unpolished energy featured before the band got married and backed off the alcohol, may be disappointed.
