Roughly a year after Avril Lavigne released her eponymous fifth album in 2013, she was diagnosed with Lyme disease. Her illness informs Head Above Water, which arrives six long years after Avril Lavigne -- the longest time separating Lavigne albums by far. Considering that half-decade gap and all the personal turmoil the singer endured, it scans that Head Above Water unveils a different Avril Lavigne, one who proudly bears her scars and is eager to share her journey. Head Above Water has its moments of darkness, but they're not sad, they're stirring. The album is designed to offer solace while also being a rallying call. Inspirational music, in other words, so it's not entirely surprising that its title track was serviced to Christian radio in advance of its release -- a gambit that proved successful, since "Head Above Water" went to number five on the Christian radio chart. Despite this, Head Above Water can't be called Christian music by any measure -- no album with "Dumb Blonde," a cherry bomb stomp of defiance featuring a Nicki Minaj verse could -- but its quieter, contemplative moments, of which there are many, do veer toward the aspirational pop of Rachel Platten, a sign Lavigne is no longer the mall punk of lore. Although the album is weighed heavily by ballads suited for adult contemporary radio, Lavigne fortunately peppers it with moments of levity: "Tell Me It's Over" sways with echoes of a '50s slow dance, "Crush" is so light it floats into the stratosphere, and "Bigger Wow" swells with strings reminiscent of vintage Vanessa Carlton. Such moments provide a needed contrast to the motivational ones while also connecting to Lavigne's bubblegum roots, a move that makes the overall maturation of the album feel earned.© Stephen Thomas Erlewine /TiVo

Part of Avril Lavigne's appeal -- a large part of it, actually -- is that she's a brat, acting younger than her 17 years on her 2002 debut, Let Go, and never seeming like she much cared about the past (she notoriously mispronounced David Bowie's name when reading Grammy nominations), or anything else for that matter. She lived for the moment; she partied with sk8er bois; she didn't want anything complicated. Thanks to production gurus the Matrix, Avril's proudly adolescent anthems were delivered in a shiny package built on steel-girded hooks -- a sound so catchy it came to define the mainstream not long after Let Go hit the radio. The Matrix became ubiquitous on the strength of their work with Lavigne, who herself became a big star, earning constant play on radio and MTV, kick starting a fashion trend of ties-n-tank tops for girls, and inexplicably providing a touchstone for indie rock queen Liz Phair's mainstream makeover. Fame, however, didn't pull the two camps together; it pushed them their separate ways, as the Matrix went on to record their own album and Avril decided to turn serious, working with a variety of co-writers and producers, including fellow Canadian singer/songwriter Chantal Kreviazuk, for her second album, 2004's Under My Skin. Lavigne hasn't only shed her trademark ties for thrift-shop skirts, she's essentially ditched the sound of Let Go, too, bringing herself closer to the mature aspirations of fellow singer/songwriter Michelle Branch. Since Avril is still a teenager, she's livelier than Branch. There may be an abundance of minor keys and midtempo cuts, but Under My Skin is fueled by teen angst; sometimes, it seems as if she's the first to discover the joys of love and the pain of heartache. In a sense, she comes across as Alanis Morissette's kid sister, especially now that the Matrix are gone and the hooks have been pushed to the background for much of the record; it's the teen spin on Supposed Former Infatuation Junkie, where she's self-consciously trying to grow as an artist. Naturally, this means that Under My Skin isn't as infectious as Let Go since there's nothing as giddy as "Sk8er Boi," even if much of it is written from a similarly adolescent vantage point. Lavigne's collaborators, Kreviazuk and Evan Taubenfeld chief among them, have helped streamline her writing via their meticulous arrangements, and her performances are assured, so Avril sounds as if she's maturing a bit. In fact, that blend of confidence and confusion gives Under My Skin its pulse; no matter how polished the surface, there's no hiding Avril's attitude and ambition.© Stephen Thomas Erlewine /TiVo

Talk about pressure -- being under 21 and having a record deal no longer qualifies as extraordinary. And as mass-produced teen pop makes its exit and a glut of young singer/songwriters enter, child prodigies no longer have built-in marketing appeal. So if newcomer, 17-year-old Avril Lavigne truly wants to be "Anything But Ordinary," as she sings on her debut album, Let Go, she'll have to dig deeper. Luckily for Lavigne, aside from youth, she does have talent. Her debut runs the gamut from driving rock numbers like "Losing Grip" -- where Lavigne shows off her vocal range, powering into the anger-fueled, explosive rock chorus -- to singer/songwriter pop tunes like "My World," where Lavigne fills listeners in on the past 17 years of her life. Lavigne handles a variety of styles deftly, but she still has some growing up to do lyrically. "Sk8er Boi" has a terrific power pop bounce, but shows her lyrical shortcomings: "He was a punk/She did ballet/What more can I say" -- a lot. The phrasing is awkward and sometimes silly: "It's funny when you think it's gonna work out/Till you chose weed over me you're so lame," she sings on "Too Much to Ask." Not surprisingly, the standout track is the first single, "Complicated," a gem of a pop/rock tune with a killer chorus. But listen carefully and you'll realize that "Complicated"'s sing-song melody borrows just enough from Pink's "Don't Let Me Get Me" to make it familiar and likeable. Nonetheless, the song is a knockout radio hit. Lavigne, a self-professed skater punk and labelmate of Pink, shares her "Take Me As I Am" credo as well. And that said, it's hard not to look at this record, executive produced by Arista label head Antonio "L.A." Reid, who is thanked by Lavigne for allowing "me to be myself," and feel cynical about the music industry's willingness to reproduce a hit over and over. Lavigne, however, is a capable songwriter with vocal chops, and at her age, one imagines, she is still finding her feet, borrowing from the music she's grown up listening to. The problem is Lavigne is still so young she's listening to the radio hits of the '90s and early 2000s: she's Pink when she's bucking authority, Alanis Morissette when she's angry, and Jewel when she's sensitive. Let Go shows promise, but the question is whether Lavigne and only Lavigne will shine through on her next effort.© Christina Saraceno /TiVo
