Given that the wave of ’90s nostalgia seems to be cresting right about now, it’s only fitting that one of that decade’s most successful and culturally ubiquitous records — Alanis Morissette’s Jagged Little Pill — is now getting the proper reissue treatment. Released in 1995, when Alanis was still an unknown here in the States, the record currently ranks among the best-selling albums of all time, having sold more than 33 million copies. Not only did the record bless us with singles that, for better or worse, will forever be a part of popular consciousness — “You Oughta Know” “Ironic,” “You Learn,” “Hand In My Pocket” — it opened the floodgates for a slew of other female solo artists who would shape the latter half of that decade. Would we have had Meredith Brooks’ “Bitch” or Paula Cole’s “I Don’t Want To Wait” without Alanis? Would Sarah McLachlan have ever gotten Lilith Fair off the ground in 1997 if Alanis hadn’t basically smashed the roof off pop culture just a couple years before? Listening to it now, it’s hard to believe that Jagged Little Pill is an album that almost wasn’t. Written when Morissette was still a teenager and rejected by almost every record label at the time, the album — which was written and produced with legendary producer and studio whiz Glen Ballard — is the kind of unlikely (ironic?) success story that becomes the stuff of legend.
