Background: Super Furry Animals are a Welsh psychedelic rock band. Since their formation in Cardiff, Wales, in 1993, the band has consisted of Gruff Rhys (lead vocals, guitar), Huw Bunford (lead guitar, vocals), Guto Pryce (bass guitar), Cian Ciaran (keyboards, synthesisers, various electronics, occasional guitar, vocals) and Dafydd Ieuan (drums, vocals). Actor Rhys Ifans is also a former member. Super Furry Animals have recorded nine UK Albums Chart Top 25 studio albums (one BPI certified Gold and four certified Silver), plus numerous singles, EPs, compilations and collaborations.
Context: In 1999, NME readers named them 'best new band' in January (this despite the fact it was now three years since they released their debut album). In May, the single "Northern Lites" was released and made No. 11 in the charts. A dense production, with steel drums clattering out a calypso rhythm whilst Rhys sang an irreverent lyric about the El Nino-Southern Oscillation weather phenomenon, it was an apt taster for the new album, Guerrilla. Recorded at the Real World Studios, the album retained SFA's pop melodies but took a less guitar-centric approach to their execution and was their most experimental work to date. Layers of samples over brass, percussion and Gruff's melodic singing produced an album which took the freewheeling approach of 1960s groups such as The Beatles, The Beach Boys and The Velvet Underground and updated it to the late 1990s. The album swung from glam and garage rock numbers ("Night Vision", "The Teacher") to novelty techno ("Wherever I Lay My Phone (That's My Home)"), ambient indietronica ("Some Things Come From Nothing") and upbeat drum and bass ("The Door To This House Remains Open"). For the cover art, Pete Fowler created the band's first three-dimensional models, rather than the paintings he had supplied for the Radiator album and singles. After playing several of the summer festivals, SFA released "Fire in My Heart", the most soulful track from Guerrilla, in August and saw it chart at No. 25. They then embarked on a US and UK tour. SFA finished their UK tour at the Cardiff International Arena in Cardiff, where they showcased the first ever concert in surround sound and broadcast it on the World Wide Web. January 2000 involved a series of changes for SFA. The last single from Guerrilla, "Do or Die", was released and made No. 20. It was also the last single SFA released on Creation Records, as founder Alan McGee set off to pursue other interests. It had always been SFA's plan to release their next album on their own label, Placid Casual, as it would be a deliberate sidestep from their recent work: a largely acoustic album of Welsh language songs entitled Mwng. Meaning "mane", its lilting melodies established that SFA's songwriting did not have to fall back on head-spinning production tricks. A limited edition (of 3000) 7 inch record, "Ysbeidiau Heulog" (meaning "Sunny Intervals") preceded Mwng in May 2000. It came backed with "Charge", a hard-rock jam recorded as a Peel Session for the BBC. The album, released the same month, sold remarkably well for a non-English LP - it made No. 11 in the charts - and received a rare distinction for a pop record, being commended in Parliament for its efforts in keeping the Welsh language alive. 2000 also saw the Furries contribute two tracks, Free Now and Peter Blake 2000, for the Liverpool Sound Collage project, which was nominated for a Grammy. They undertook this remixing of unreleased Beatles recordings at the invitation of Paul McCartney, whom they had met at the NME Awards, where they had won Best Live Act.
Question: What is Guerrilla?
Answer: the new album, Guerrilla.

Background: Expose is an American Latin freestyle vocal group. Primarily consisting of lead vocalists Jeanette Jurado, Ann Curless, and Gioia Bruno, the group achieved much of their success between 1984 and 1993, becoming the first group to have four top ten hits on the Billboard Hot 100 chart from its debut album, including the 1988 #1 hit "Seasons Change". In March 2015, Billboard magazine named the group the eighth most-successful girl group of all-time. The group was popular in dance clubs, mainstream Top 40 and adult contemporary charts in the United States.
Context: In March 1987, the new lineup of Expose released its debut album Exposure on Arista Records, led by the pop/dance hit "Come Go with Me" which reached #5 on the US Billboard Hot 100 chart. During the summer of 1987, a re-recorded version of "Point of No Return" was released, with Jurado now performing lead vocals, and it too topped out at #5 on the US Hot 100. While the initial distribution of Exposure to suppliers contained the original 1984 version of that song, subsequent pressings contained the new version. "Let Me Be the One", a mid-tempo R&B song with Bruno on lead vocal, became yet another hit reaching #7 on the US Hot 100 and also garnering significant R&B radio airplay. The group's highest charting hit occurred in February 1988 with the #1 US hit ballad "Seasons Change". Along with that came a Soul Train Award nomination for Best New Artist; television appearances on American Bandstand, Solid Gold, Showtime at the Apollo, and The Late Show Starring Joan Rivers; and the group was tapped to be the opening act for Lisa Lisa and Cult Jam during its national tour. Expose also performed backing vocals on Kashif's 1987 Arista/BMG Records album Love Changes, on the song "Who's Getting Serious?". During Expose's peak, the group endured legal issues behind the scenes. The members had a restrictive contract and there were reports in the media of backstage battles. According to Bruno, they were only paid $200 per show. Reportedly, the record label had to intervene to try to keep the peace between the members and their producers. Despite this intervention, the members filed a lawsuit and ultimately settled their legal case for a renegotiated contract.
Question: Did they have any other hits that got the US Hot 100?
Answer:
The group's highest charting hit occurred in February 1988 with the #1 US hit ballad "Seasons Change".
