Problem: Queens of the Stone Age are an American rock band formed in 1996 in Palm Desert, California. The band's line-up includes founder Josh Homme (lead vocals, guitar, piano), alongside band members Troy Van Leeuwen (guitar, lap steel, keyboard, percussion, backing vocals), Michael Shuman (bass guitar, keyboard, backing vocals), Dean Fertita (keyboards, guitar, percussion, backing vocals), and Jon Theodore (drums, percussion). Formed after the dissolution of Homme's previous band, Kyuss, Queens of the Stone Age developed a style of riff-oriented, heavy rock music. Their sound has since evolved to incorporate a variety of different styles and influences, including working with ZZ Top member Billy Gibbons, Nirvana drummer and Foo Fighters frontman Dave Grohl, and Screaming Trees frontman Mark Lanegan who has been a steady contributor to the band.

After the breakup of his previous band, Kyuss, in 1995, Josh Homme briefly joined Screaming Trees as a touring guitarist, before deciding to form a new band, Gamma Ray. In 1996 they released the eponymous Gamma Ray EP, featuring "Born to Hula" and "If Only Everything" (which would later appear on their self-titled debut as 'If Only'). The EP featured Matt Cameron of Soundgarden and Pearl Jam, Van Conner from Screaming Trees, and percussionist Victor Indrizzo. Gamma Ray changed their name in 1997 after the German power metal band Gamma Ray threatened to sue. The name "Queens of the Stone Age" came from a nickname given to Kyuss by their producer Chris Goss. Homme said of the name: "Kings would be too macho. The Kings of the Stone Age wear armor and have axes and wrestle. The Queens of the Stone Age hang out with the Kings of the Stone Age's girlfriends when they wrestle ... Rock should be heavy enough for the boys and sweet enough for the girls. That way everyone's happy and it's more of a party. Kings of the Stone Age is too lopsided." The first release under the Queens of the Stone Age name was the song "18 A.D.," released on the compilation album Burn One Up! Music for Stoners which featured members of the Dutch stoner rock band Beaver. The band's first live appearance was on November 20, 1997, at OK Hotel in Seattle, Washington, with Cameron on drums, Mike Johnson of Dinosaur Jr. on bass and John McBain of Monster Magnet on guitar. In December that year, the band released a split EP, Kyuss/Queens of the Stone Age, which featured three tracks from the Gamma Ray sessions as well as three Kyuss tracks recorded in 1995 prior to their breakup. Queens of the Stone Age released their self-titled debut in 1998 on Stone Gossard's and Regan Hagar's label Loosegroove Records, and on vinyl by Man's Ruin Records. Homme played guitar and bass on the album (the latter credited to Homme's alter-ego Carlo Von Sexron), Alfredo Hernandez on the drums, and several other contributions by Chris Goss and Hutch. Homme reportedly asked Screaming Trees vocalist Mark Lanegan to appear on the record, but he was unable due to other commitments. Soon after the recording sessions were finished for the album, former Kyuss bassist Nick Oliveri joined the group, and touring commenced with a band consisting entirely of ex-Kyuss members. Guitarist Dave Catching joined shortly after. From this point forward, the band's line-up would change frequently; by the time their second album was being recorded, Hernandez had left the group to play in other bands.

Did they collaborate with any notable artists for their debut album?

Answer with quotes: drums, and several other contributions by Chris Goss and Hutch.

Problem: The Moody Blues are an English rock band formed in Birmingham, England in 1964. They first came to prominence playing rhythm and blues music, but their second album, Days of Future Passed, which was released in 1967, was a fusion of rock with classical music and established them as pioneers in the development of art rock and progressive rock. It has been described as a "landmark" and "one of the first successful concept albums". The band became known internationally with singles including "Go Now", "Nights in White Satin", "Tuesday Afternoon", and "Question".

In the spring of 1974, after completing a vast world tour that culminated with a tour of Asia, the group took an extended break, erroneously reported as a break-up at the time, because of the other band members feeling exhausted and overshadowed (this was said by Hayward in the final issue of Higher & Higher magazine 2006). Although the band had typically featured four lead vocalists (with Edge also contributing vocally), Hayward was the principal guitarist/vocalist whilst Pinder was considered to be the person most responsible for their symphonic sound, arrangements, and overall conceptual direction. Pinder and Thomas also doubled as the Moodies' onstage MCs (as the 1969 "Caught Live + 5" album displayed). Before the band's 1973-74 world tour (their last with Pinder), Hayward wrote a song called "Island" with the intention of including it on a potential follow-up album, which the Moodies recorded in 1973 before ultimately going their separate ways. An additional cause of the hiatus were the long tours that had by this time strained Pinder, who needed a rest. In 1974 the band oversaw preparation of the compilation album This Is The Moody Blues which was released that year. Hayward and Lodge released a duo album, the very successful Blue Jays (1975), and a UK chart single, "Blue Guitar" (no. 8), which was credited to Hayward and Lodge even though it was just Hayward with 10cc backing him. The album had originally been a projected liaison between Hayward and Pinder, but after Pinder dropped out, John Lodge stepped in. (Tony Clarke produced it.) The members then released solo albums. Pinder said he hoped to get the band back together that year. "Having moved to California in 1974, I returned to Britain for a visit in summer 1975. I was trying to get the band to do an album, but the response was so weak I returned to California with my two new Mk5 mellotrons and began work on my solo album The Promise." Edge produced two albums with guitarist Adrian Gurvitz, Kick Off Your Muddy Boots (1975) and Paradise Ballroom (1976); Hayward composed the acoustically textured Songwriter (1977), which was followed up in later years by Night Flight (1980), Moving Mountains (1985), (which Hayward dedicated to Peter Knight) Classic Blue (1989), The View From The Hill (1996) and Live in San Juan Capistrano (1998); Lodge released Natural Avenue (1977); Pinder produced The Promise (1976); and Thomas collaborated on two projects with songwriter Nicky James, producing From Mighty Oaks (1975) and Hopes, Wishes and Dreams (1976).
