Task: Explanation
Input (English): 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. 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 Answer: Los Lobos
Output (English):  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.
