Given the following context:

Stereolab alumni have also founded bands of their own. Guitarist Tim Gane founded the side project Cavern of Anti-Matter and also formed Turn On alongside band member Sean O'Hagan, who formed his own band the High Llamas. Katharine Gifford formed Snowpony with former My Bloody Valentine bassist Debbie Googe. Sadier has released three albums with her four-piece side-project Monade, whose sound Mark Jenkins called a "little more Parisian" than Stereolab's. Backing vocalist Mary Hansen formed a band named Schema with members of Hovercraft and released their eponymous EP in 2000.As of August 1999, US album sales stood at 300,000 copies sold. Despite receiving critical acclaim and a sizeable fanbase, commercial success eluded the group. Early in their career, their 1993 EP Jenny Ondioline entered the UK Singles Chart, but financial issues prevented the band from printing enough records to satisfy demand. When Elektra Records was closed down by Warner Bros. Records in 2004, Stereolab was dropped along with many other artists, reportedly because of poor sales. Tim Gane said in retrospect that that the group "signed to Elektra because we thought we would be on there for an album or two and then we'd get ejected. We were surprised when we got to our first album!" Since then, Stereolab's self-owned label Duophonic has inked a worldwide distribution deal with independent label Too Pure. Through Duophonic, the band both licenses their music and releases it directly (depending on geographic market). Gane said, "... we license our recordings and just give them to people, then we don't have to ask for permission if we want to use it. We just want to be in control of our own music."In hip-hop culture, the song "Come And Play in the Milky Night" was sampled by American producer J Dilla for "Show Me What You Got" by Busta Rhymes, Sadier was featured in the track "PartyIsntOver/Campfire/Bimmer" by Tyler, The Creator in his Wolf album, and Pharrell Williams "is a fan" of the song "The Flower Called Nowhere".

What band had US album sales of 300,000 as of August 1999?
