Question: What rock band topped the charts with their cover of "La Bamba" in 1987 and had a band member with a guest appearance on Dolly Parton's "Treasures" in 1996
Context: 9 to 5 and Odd Jobs is the 23rd solo studio album by Dolly Parton, and was released in late 1980.  A concept album about working, the album was centered on Parton's hit "9 to 5", which served as the theme song to the film of the same name (co-starring Parton, Jane Fonda and Lily Tomlin), and topped both the U.S. country and pop charts.  The album's two additional singles—a cover of Mike Settle's "But You Know I Love You" and a reading of "The House of the Rising Sun" – provided further country hits, with "But You Know I Love You" also reaching #1. "Real Love" is a song written by David Malloy, Richard "Spady" Brannon and Randy McCormick, and recorded as a duet by American entertainers Dolly Parton and Kenny Rogers that topped the U.S. country singles charts in August 1985.  It was released in May 1985 the second single and title track from Parton's "Real Love" album.  Released after the top-ten success of "Don't Call It Love", the song became Parton and Rogers' second country chart-topper as a duet act.  However, "Real Love" did not fare as well on the pop singles charts as 1983's "Islands in the Stream" had done, stalling at number 91 on the "Billboard" Hot 100 and number 13 on the Adult Contemporary chart. Treasures is a 1996 Dolly Parton album, made up of covers of rock and country hits from the 1960s, 1970s and 1980s.  It was her 33rd studio album.  Among the selections were work by Merle Haggard, Jeanne Pruett, Neil Young, Kris Kristofferson, Cat Stevens and Mac Davis.  Perhaps the most surprising choices to fans were Young's "After the Gold Rush" and Stevens' "Peace Train", though Parton confessed a longtime admiration for both performers' work.  (She had also recorded "After the Gold Rush" in 1994 with Linda Ronstadt and Emmylou Harris as part of the "Trio 2" album, though as of "Treasures"' release, the "Trio" recording had not yet been released.)  The album received mixed reviews and reached number 24 on the U.S. country albums charts.  "Treasures" featured a number of famous guest artists, including Ladysmith Black Mambazo, John Popper of Blues Traveler, David Hidalgo of Los Lobos, and Alison Krauss. Eagle When She Flies is Dolly Parton's 30th solo studio album, released on April 6, 1991.  Continuing the country sounds of 1989's "White Limozeen", the album featured collaborations with Lorrie Morgan and Ricky Van Shelton; additional supporting vocals were provided by Vince Gill and Emmylou Harris.  Dolly Parton's duet with Shelton, "Rockin' Years", topped the country charts, and the follow-up single co-written by Carl Perkins, "Silver and Gold", was a #15 country single.  Rounding out the hit singles was the title song "Eagle When She Flies", which only reached a #33 peak, despite spending 20 weeks on the Billboard Country Singles chart.  Her duet with Lorrie Morgan, "Best Woman Wins", appeared simultaneously on Lorrie Morgan's 1991 album "Something in Red".  She co-wrote the song "Family" with Carl Perkins and "Wildest Dreams" with Mac Davis.  The album also topped the U.S. country albums charts, Parton's first solo album to reach the top in a decade (and her last to do so until 2016) and reached #24 on the pop albums charts.  The album spent 73 weeks on the Billboard Top Country Albums chart.  It was her first album to reach number one album in the United States after 1980's "9 to 5 and Odd Jobs." "La Bamba" has been covered by numerous artists, most notably by Los Lobos, whose version was the title track of the 1987 film "La Bamba" and reached No. 1 in the U.S. and UK singles charts in the same year.  The Los Lobos version remained No. 1 for three weeks in the summer of 1987.  The music video for Los Lobos' version, directed by Sherman Halsey, won the 1988 MTV Video Music Award for Best Video from a Film. "Old Flames (Can't Hold a Candle to You)" is a country song written by singer-songwriter Pebe Sebert and Hugh Moffatt.  It was a number 14 U.S. country hit for Joe Sun in 1978, and a number 86 hit for Brian Collins the same year.  It was later covered by Dolly Parton, who took it to the top of the U.S. country singles charts in August 1980. .  Parton included her version on her 1980 "Dolly, Dolly, Dolly" album, and it was released as the album's second single after the success of "Starting Over Again".  In 2013, Sebert's daughter, Kesha, released an acoustic cover of the song as part of her extended play "Deconstructed".  A new version featuring Parton is on a track of Kesha's 2017 album "Rainbow". "Please Don't Stop Loving Me" is a song written and recorded as a duet by American country music artists Porter Wagoner and Dolly Parton.  It was released in July 1974 as the first single from the album "Porter 'n' Dolly".  "Please Don't Stop Loving Me" was Porter Wagoner and Dolly Parton's sixteenth country hit and their only number one on the country chart as a duet act.  Though Parton and Wagoner had each topped the charts as solo artists, and many of their duet singles had reached the country top-ten, "Please Don't Stop Loving Me" was their only chart-topper as a duet act.  The single stayed at number one for one week and spent a total of ten weeks on the country chart. Los Lobos (] , Spanish for "the Wolves") is an American rock band from East Los Angeles, California, United States.  Their music is influenced by rock and roll, Tex-Mex, country, zydeco, folk, R&B, blues, brown-eyed soul, and traditional music such as cumbia, boleros and norteños.  It gained international stardom in 1987, when their cover version of Ritchie Valens' "La Bamba" topped the charts in the U.S., the UK and several other countries.  In 2015, it was nominated for induction into the Rock and Roll Hall of Fame. Heartbreaker is the 20th solo studio album by Dolly Parton, released in 1978.  Released following the huge pop crossover success of "Here You Come Again", "Heartbreaker" was designed as an even more direct aim at the pop charts, with several of its songs verging on disco.  The title song, a ballad written by Carole Bayer Sager, topped the U.S. country charts, and became Parton's third top-forty pop hit, while the follow-up single was the double-A-sided "Baby I'm Burning"/"I Really Got the Feeling", with "Baby I'm Burnin'" targeted for pop airplay, and "I Really Got the Feeling" for country.  The formula (which had previously worked for "Here You Come Again"'s double-A-sided "Two Doors Down"/"It's All Wrong, but It's All Right") was successful again, with the single reaching #1 on the country charts, and #25 on the pop charts. Dolly, Dolly, Dolly, released in 1980, is the 22nd solo studio album by Dolly Parton.  Coming at the height of her late 1970s-1980s quest for pop success, the album was her least traditional country-sounding album to that point, with a number of songs bordering on disco.  Though the album's two singles, "Starting Over Again" (written by Donna Summer and Bruce Sudano) and "Old Flames Can't Hold a Candle to You" topped the U.S. country charts ("Starting Over Again" also hit #36 on the pop charts), the album is generally regarded by critics, as well as Parton's fans, as one of the least satisfying albums of her career; it was almost universally panned at the time of its release; of the major press, only "People Magazine" reviewed it favorably.  The album was noteworthy for being one of the only Parton albums to that point not to include a single of her own compositions; it was composed entirely of covers.
Answer: Los Lobos
