Belle & Sebastian's career can be separated into two eras: from 1996's Tigermilk through 2002's Storytelling soundtrack, when they defined twee and shunned the press or even showing their faces; and from 2003's Dear Catastrophe Waitress and on, after they lost founding member Isobel Campbell but gained a swagger absent from their earlier work. The Third Eye Centre collects remixes and B-sides from this second era of the band. B&S have always been a classically minded band, putting some of their best songs on B-sides a la their heroes in bands like The Smiths, which makes The Third Eye Centre every bit as eventful as one of their full-length releases. The double-length set starts with a remix of "I'm a Cuckoo" by the Avalanches that turns the bookish, Thin Lizzy-reffing indie rocker into a Franco-Afropop wonder, with flutes, accordion, chants and syncopated rhythm. B-side "Suicide Girl" is a catchy new waver about a tattooed hopeful for the forgotten site of alt pinups. The '60s-flavored pop of old B&S returns on songs like the swanky "Love on the March," Mamas & the Papas-ish "Last Trip" and summer-of-love-style "Your Secrets." The Third Eye Centre doesn't always hang together well as a collection — the Miaoux Miaoux remix of beloved B-side "Your Cover's Blown" is a highlight, but it doesn't jibe well with the low-key pop of much of the rest of the songs — but its individual parts are greater than the sum. Its later tracks offer bits and pieces that harken back to the band's older days, like the wintry, Sarah Martin-led "Heaven in the Afternoon," while others show even more directions the band has tried out in its second incarnation, like the Paul Simonisms of "Mr Richard." It's easy to forget how much ground Belle & Sebastian has covered in its nearly 20 years of existence, but The Third Eye Centre reminds us of just how great and diverse this band is. Until their next release comes, it's a sweet wave of twee-pop goodness to tide us over.
