Problem: Background: Eric Garth Hudson (born August 2, 1937) is a Canadian multi-instrumentalist. As the organist, keyboardist and saxophonist for Canadian-American rock group the Band, he was a principal architect of the group's unique sound. Hudson has been called "the most brilliant organist in the rock world" by Keyboard magazine. As of 2018, Hudson and fellow musician Robbie Robertson are the last original members of The Band who are still alive.
Context: Under the strict supervision of Hawkins, the Hawks became an accomplished band. They split from Hawkins in 1963, recorded two singles and toured almost continually, playing in bars and clubs, usually billed as Levon and the Hawks. Hudson started work as a session musician in 1965, playing on John Hammond, Jr.'s So Many Roads along with Robertson (guitar) and Helm (drums).  In August 1965, they were introduced to Bob Dylan by manager Albert Grossman's assistant, Mary Martin. In October, Dylan and the Hawks recorded the single "Can You Please Crawl Out Your Window?", and in January 1966 they recorded material with Dylan for what would turn into the Blonde on Blonde album. Dylan recruited the band to accompany him on his controversial 1966 "electric" tour of the United States, Australia and Europe. (An album of Dylan's 1966 performance with his band, The "Royal Albert Hall" Concert, was finally released in 1998.) Subsequent to Bob Dylan's motorcycle accident in July 1966, the group settled in a pink house in West Saugerties, New York, near Woodstock. Dylan was a frequent visitor, and Hudson's recordings of their collaborations resulted in The Basement Tapes.  By 1968, the group recorded its debut album, Music from Big Pink. The album was recorded in Los Angeles (at Capitol) and New York (at A&R Studio). Capitol originally announced that the group would be called the Crackers, but when Music From Big Pink was released they were officially named the Band. The album includes Hudson's organ showcase, "Chest Fever", a song that in the Band's live shows would be vastly expanded by a solo organ introduction, entitled "The Genetic Method", an improvisational work that would be played differently at each performance. An example can be heard on the live album Rock of Ages. Hudson is also adept at the accordion, which he played on some of the group's recordings, such as "Rockin Chair", from "The Band"; the traditional "Ain't No More Cane", from "The Basement Tapes"; Dylan's "When I Paint My Masterpiece"; and Bobby Charles's "Down South in New Orleans" during the Last Waltz. His saxophone solo work can be heard on such songs as "Tears of Rage" (from Big Pink) and "Unfaithful Servant" (from The Band). Hudson is credited with playing all of the brass and woodwinds on the studio version of "Ophelia", from the 1975 album Northern Lights - Southern Cross as well. This album, the first to be recorded in the Band's Shangri-La recording studio in Malibu, California, also saw Hudson adding synthesizers to his arsenal of instruments.  Hudson provided innovative accompaniment. For example, the song "Up on Cripple Creek" features Hudson playing a clavinet through a wah-wah pedal to create a swampy sound reminiscent of a Jew's harp or the croak of a frog. This clavinet-wah wah pedal configuration was later adopted by many funk musicians.  After years of continuous touring, the Band made its final bow as a touring band with a lavish final concert on Thanksgiving Day 1976 at the Winterland Ballroom in San Francisco, an all-star tribute concert documented in The Last Waltz.
Question: Who were members of the band?
Answer: Robertson (guitar) and Helm (drums).

Problem: Background: Testament is an American thrash metal band from Berkeley, California. Formed in 1983 under the name Legacy, the band's current lineup comprises guitarists Eric Peterson and Alex Skolnick, lead vocalist Chuck Billy, drummer Gene Hoglan, and bassist Steve Di Giorgio. Since its inception, Testament has had numerous lineup changes, leaving Peterson as the only constant member. Billy replaced original singer Steve "Zetro" Souza (who left the band to join Exodus as the replacement of Paul Baloff) in 1986, prior to the recording of their first studio album, The Legacy, and has been a member of the band since.
Context: As early as 2009, Testament commenced writing new material for their tenth album. In an interview with Metalheadz, guitarist Eric Peterson stated that there were about four songs written and that "there's other guys in the band who like to play the more rock melodic style but the next one is gonna be a bit heavier." In a January 2011 interview during the 70000 Tons of Metal cruise, frontman Chuck Billy revealed that Testament had been working on six new songs, with four or five "maybe left to write," and would begin recording their new album by early March. On 18 May 2011, guitarist Alex Skolnick posted an update on his Twitter, saying, "Another tune done! My riffs from last week [plus] some of [fellow Testament guitarist Eric Peterson's plus] new ones we wrote today. Planning one more, then we've got more than we need."  Testament began recording their tenth studio album on June 20, 2011. Drummer Paul Bostaph was unable to take part in the recording due to a "serious injury", although he was expected to rejoin when the band tours to support the album. Gene Hoglan, who played drums on the band's 1997 album Demonic, filled in for Bostaph. It was also reported that Lamb of God drummer Chris Adler would make a special guest appearance on a couple of bonus tracks.  Testament appeared at the California dates of the summer 2011 Rockstar Energy Drink Mayhem Festival, replacing In Flames.  On 14 July 2011, it was announced that the tenth Testament studio album would be called Dark Roots of Earth, which, after many delays, was released on July 27, 2012. Dark Roots of Earth debuted at No. 12 on Billboard 200, the band's highest chart position to date. Prior to the album's release, the band toured in the fall of 2011 with Anthrax and Death Angel. Overkill was invited to the tour, but due to the pre-production of their sixteenth studio album The Electric Age, they did not participate. It was announced on 1 December 2011 that Paul Bostaph had left Testament. Gene Hoglan recorded the drum tracks for Dark Roots of Earth and continues to play live with the band. In interviews, Testament have expressed pleasure in Hoglan's playing, and hope that he would continue playing with the band for the foreseeable future.
