Although Spiritualized fully emerged after the acrimonious breakup of Spacemen 3, in truth the band's roots extended back to the band's final LP, 1990's Recurring. A Spacemen 3 album in name only, Recurring was split evenly between independently recorded work from Pierce and estranged partner Pete "Sonic Boom" Kember; as a result, while Kember's side presaged his eventual work with Spectrum, Pierce's half, recorded with most of the musicians who would later comprise Spiritualized (including guitarist Mark Refoy, bassist Willie B. Carruthers, and drummer Jon Mattock), predated the orchestral drones that became the band's hallmark. The first true Spiritualized single, a dramatic reading of the Troggs' "Anyway That You Want Me," was the final nail in the coffin -- reportedly, Kember was so incensed by the Spacemen 3 logo which appeared on the disc's jacket that he disbanded the group for good.

In 1991, Spiritualized returned with a string of EPs -- Feel So Sad, Run/I Want You, and Smile/Sway -- before their long-awaited debut, Lazer Guided Melodies, finally appeared the following year. The masterful, blissed-out result of Pierce's obsessive studio fine-tuning and endless remixing, the album was promoted by the band's slot on the high-profile Rollercoaster tour, where they appeared with the Jesus and Mary Chain and Curve. An excellent limited-edition live document, Fucked Up Inside, followed in 1993, trailed by another EP, Electric Mainline, later in the year.

In 1995, Spiritualized -- now a trio consisting of Pierce, keyboardist/guitarist Kate Radley, and bassist Sean Cook -- issued Pure Phase, a heady, dense production which boasted separate mixes from each stereo channel. With 1997's Ladies and Gentlemen We Are Floating in Space, Pierce deliberately jettisoned many of the band's usual points of departure, including drones, tremolos, and phase tones; recorded with new drummer Damon Reece, it featured a cameo appearance from legendary New Orleans pianist Dr. John on one track, while Memphis studio legend Jim Dickinson appeared on another. Other guests included the Balanescu Quartet (also featured on Pure Phase), the London Community Gospel Choir, and Spring Heel Jack. The two-disc Royal Albert Hall October 10 1997 live album followed in late 1998.

The following year, Pierce gutted Spiritualized's lineup, firing Cook, Reece, and Mike Mooney, who formed Lupine Howl soon after their dismissal; Radley apparently left soon after she married Verve frontman and solo artist Richard Ashcroft. Only saxophonist Ray Dickaty and sometime keyboardist Thighpaulsandra (aka Tim Lewis) remained in the band. Pierce began writing and recording material for the next Spiritualized album at George Martin's Air Studios and recruited percussionist Tom Edwards, bassist Martin Shallards, Echoboy drummer Kev Bales, and guitarist Dogan, from Julian Cope's band, for the sessions. The new album, Let It Come Down, which featured an even lusher, more involved sound than Ladies and Gentlemen, was released in mid-2001. The follow-up, 2003's Amazing Grace, was more of a back-to-basics record. Songs in A and E arrived in spring 2008. In 2010, the band embarked on a tour performing Ladies and Gentlemen ... in its entirety, writing new songs influenced by that album -- as well as by the Beach Boys and Peter Brötzmann -- while they were on the road. Pierce and company laid the songs down at studios in Los Angeles, Wales and Reykjavik over the course of two years; the results, Sweet Heart Sweet Light, were released in March 2012.
