by Stephen Thomas Erlewine & Wade Kergan Combining an inclination for melodic 60s pop with an art rock aesthetic borrowed from Krautrock bands like Faust and Neu!, Stereolab were one of the most influential alternative bands of the 90s. Led by Tim Gane and Laetitia Sadier, Stereolab either legitimized forms of music that were on the fringe of rock, or brought attention to strands of pop music — bossa nova, lounge-pop, movie soundtracks — that were traditionally banished from the rock lineage. The groups trademark sound — a droning, hypnotic rhythm track overlaid with melodic, mesmerizing singsong vocals, often sung in French and often promoting revolutionary, Marxist politics — was deceptively simple, providing the basis for a wide array of stylistic experiments over the course of their prolific career. Throughout it all, Stereolab relied heavily on forgotten methods of recording, whether it was analog synthesizers and electronics or a fondness for hi-fi test records, without ever sinking to the level of kitsch. Tim Gane (born July 12, 1964; guitar, keyboards) was the leader of McCarthy, a London-based band from the late 80s that functioned as a prototype for Stereolabs sound. Gane met Laetitia Sadier (born May 6, 1968; vocals, keyboards), a French-born vocalist, at one of McCarthys concerts. The pair began a romantic relationship that became a musical collaboration after McCarthy disbanded in 1990; Sadier did sing on the final McCarthy album. The duo began releasing mail-order singles under the name Stereolab, borrowing their name from a form of record mastering from the late 50s. At that point, the group was working with Th Faith Healers drummer Joe Dilworth and former Chills bassist Martin Kean; Gina Morris occasionally provided backup vocals. All three singles this incarnation of Stereolab released were compiled on Switched On, an album released on Too Pure Records in 1992. Switched On was released at the same time as the bands official debut album, Peng! Both albums featured a variation on a maniacally grinning cartoon, which was their only visual trademark at the time. Switched On and Peng!, along with the 1992 Lo-Fi EP and a series of limited-edition singles like John Cage Bubblegum — which, coincidentally, was the first Stereolab recording to feature keyboardist/vocalist Mary Hansen and drummer Andy Ramsay, who became two of the groups core members — Stereolab carved out a cult following, particularly in the U.K. underground. Released in early 1993, The Groop Played Space Age Batchelor Pad Music featured the core group of Gane, Sadier, Hansen, and Ramsay, along with ex-Microdisney guitarist Sean OHagan and bassist Duncan Brown. One of the first 90s alternative records to explicitly draw from the Space Age lounge-pop music of the 50s, The Groop became an underground sensation, paving the way toward Stereolabs first American record contract with Elektra Records. But before the band made their major-label debut, they released the split 10 EP Crumb Duck with Nurse with Wound in the summer of 1993 and formed their own U.K. label, Duophonic. Stereolabs next album, and their first American release, was Transient Random-Noise Bursts With Announcements. Released in the fall of 1993, Transient became an underground and college hit throughout the U.S. and U.K., and Stereolab soon became a hip name to drop for many musicians, including Sonic Youth, Pavement, and Blur, who had Laetitia Sadier provide guest vocals on their 1994 hit single To the End. Where Transient was dominated by a lo-fi experimentalism, the groups sound became lusher and more layered with Mars Audiac Quintet, which was released in the fall of 1994. OHagan moved from a full member to a part-time guest during the recording of the album — he was busy forming his own band, the High Llamas — and the band added keyboardist Katherine Gifford. By the time of Mars Audiac Quintets release, the Stereolab sound had become prominent throughout the underground, and the group began to make efforts to change their sound, as the limited-edition 1995 EP Music for the Amorphous Body Study Centre indicated. Created for an interactive art exhibit by Charles Long, the EP boasted detailed, intricate string and vocal arrangements which were more sophisticated than the groups previous releases. That fall, the band rounded up a bunch of singles and B-sides for the second Switched On compilation, Refried Ectoplasm, which was released on Drag City in the U.S. Before the band recorded a new album, Gifford was replaced by Morgane Lhote. Emperor Tomato Ketchup, released in the spring of 1996, was a break from the drone rock of its two predecessors, demonstrating a heavy hip-hop, jazz, and dance influence. The album was the greatest success to date, earning positive reviews in both U.S. and U.K. and becoming a significant college hit in the process. After the recording of Emperor Tomato Ketchup, bassist Duncan Brown was replaced by Richard Harrison. At the end of 1996, Stereolab released the limited-edition, horn-driven Fluorescences EP. Dots and Loops appeared a year later and, like Emperor Tomato Ketchup before it, featured the production and playing of Tortoises John McEntire. Further bolstering the Stereolab lineup for Dots and Loops was German techno-pop refugee Jan St. Werner of Mouse on Mars.
