Essentially, LeAnn Rimes is a covers album, with one new song ("Big Deal") tacked onto the end, which makes it a return to her roots -- which, in turn, means that it's sort of a salute to her main influence, Patsy Cline.

Rimes tackles no less than five songs from Cline's 12 Greatest Hits, plus "Lovesick Blues," which Cline also recorded.

It's a tricky situation for a singer pegged as a Cline soundalike with her first hit single, "Blue." If those comparisons bother Rimes, it's impossible to tell from her performance, since she sings these six songs exactly like Cline does.

As it turns out, imitation is a crutch Rimes uses quite often, since she mimics Janis Joplin on "Me and Bobby McGee" and pretty much uses Marty Robbins as a guide vocal on "Don't Worry." Since she has a good voice and these are, by and large, great songs, it's hard to complain -- given the best set of songs of her career, she delivers good, professional performances, stumbling only on "Me and Bobby McGee" with Joplin-like histrionics.

So, LeAnn Rimes winds up being one of her better efforts, even if her vocals are fairly mannered and the arrangements are fairly predictable.

But the most curious thing about this covers album is that Rimes turns in her best performance on the lone new track.

She sounds loose, confident and exciting on "Big Deal," and even more importantly, she never sounds like one of her idols -- she sounds like herself.

And since it comes at the end of the record, you can't help but wish she'd recorded an album of new, pure country songs as good as "Big Deal" instead of a collection of covers, no matter how well she sang those covers.
