Alanis Morissette, 02 Arena, London, review The country is currently gripped in a Nineties revival: grunge is back in fashion, there's a Spice Girls musical in the West End, bands such as The Stone Roses have returned to the stage. If ever there was a time for a middle-aged Alanis Morissette to play a whopping great venue such as the O2 Arena, it's now. But the Canadian singer is not just enjoying a revival. For her fiercely loyal fans, she never went away. Her eighth album, Havoc and Bright Lights, was released in August, her first since leaving long-time label Maverick (something she told the Telegraph earlier this year that she was exceptionally relieved by). At the age of 38, she maintains her Alanis Morissette look - her flowing brown hair still tumbles down her back, and her outfit at the O2 contained just a hint of rock star in her glittery grey jeans and black shirt. But, unlike the 21-year-old who released the enormously successful rock album Jagged Little Pill back in 1995, Morissette is a woman who is no longer angry. Once known for her savagely honest, vitriolic and introspective lyrics - often inspired by the break-up of former relationships - she has become a happily married mother. What we saw on stage was a relaxed Morissette, who cheerfully gave a nod to her son as she coyly adjusted the lyrics of the classic You Learn to "Wear it out, the way a two-year-old would do." Indeed, her new material is mellower in tone - gone are the sharp quips about oral sex in theatres - but that's not to suggest that Morissette has nothing left to say. Among the many new tracks in this set, Woman Down delivered a commanding anti-domestic violence message, while Guardian proved a heart-warming ode to motherhood. Spending the majority of her performance striding back and forth across the stage - with such a frequency that it became distracting - Morissette was at her most enthralling when doing something different, be it leading a jubilant crowd in a singalong of her biggest hit, Ironic, or putting her mane to full use by fiercely headbanging to Uninvited. It was the two-song acoustic section towards the end which best showcased her remarkable vocal talent. Sat atop a tall chair, ankle resting on her knee, she belted out Hand in My Pocket and the enchanting a cappella track Your House, bringing the huge crowd to near silence. Mellow she may be these days, but Morissette can still command the attention of thousands with nothing but the power of her voice.
