“ALL I’ve got is precious time,” W. Axl Rose sings in the title song of Guns N’ Roses’ new album, and he must be well aware of how that line sounds now. Mr. Rose, 46, the only remaining original member of Guns N’ Roses, needed 17 years, more than $13 million (as of 2005) and a battalion of musicians, producers and advisers to deliver “Chinese Democracy,” the first album of new Guns N’ Roses songs since 1991. It’s being released on Sunday, with CDs sold exclusively at Best Buy. (In another 21st-century fillip the album’s best song, “Shackler’s Revenge,” appeared first in a video game, Rock Band 2.)

“Chinese Democracy” (Geffen) is the Titanic of rock albums: the ship, not the movie, although like the film it’s a monumental studio production. It’s outsize, lavish, obsessive, technologically advanced and, all too clearly, the end of an era. It’s also a shipwreck, capsized by pretensions and top-heavy production. In its 14 songs there are glimpses of heartfelt ferocity and despair, along with bursts of remarkable musicianship. But they are overwhelmed by countless layers of studio diddling and a tone of curdled self-pity. The album concludes with five bombastic power ballads in a row.

“Chinese Democracy” sounds like a loud last gasp from the reign of the indulged pop star: the kind of musician whose blockbuster early success could once assure loyal audiences, bountiful royalties, escalating ambitions and dangerously open-ended deadlines. The leaner, leakier 21st-century recording business is far less likely to nurture such erratic perfectionists. (Mr. Rose did manage to outpace Kevin Shields of My Bloody Valentine, which re-emerged on tour this year but hasn’t yet released a successor to its 1991 masterpiece, “Loveless.”) The new rock paradigm, a throwback to the 1950s and early 1960s, is to record faster, more cheaply and more often, then head out on tour before the next YouTube sensation distracts potential fans.

“Chinese Democracy” is such an old-school event that at this point no album could easily live up to the pent-up anticipation and fascination. Over the last two decades Guns N’ Roses’ 1987 debut album, “Appetite for Destruction,” has sold 18 million copies in the United States alone. The original band, particularly the guitar team of Slash on lead and Izzy Stradlin on rhythm, collaborated to forge a scrappy combination of glam, punk and metal behind Mr. Rose’s proudly abrasive voice, which could leap from a baritone growl to a fierce screech. Singing about sex, drugs, booze and stardom, Mr. Rose was a rags-to-MTV success story for the 1980s: a self-described abused child from heartland America who got himself out of Indiana and reinvented himself as a full-fledged Hollywood rock star, charismatic and volatile, never pretending to be controllable.
