Background: Alicia Augello Cook (born January 25, 1981), known professionally as Alicia Keys, is an American singer-songwriter, pianist, music producer, philanthropist, and actress. Keys released her debut album, Songs in A Minor in 2001 with J Records, having had previous record deals first with Columbia and then Arista Records. Songs in A Minor produced her first Billboard Hot 100 number-one single "Fallin'", and sold over 12 million copies worldwide. The album earned Keys five Grammy Awards in 2002.
Context: Following Davis to his newly formed J Records label, she worked with Kerry "Krucial" Brothers and recorded the songs "Rock wit U" and "Rear View Mirror", which were featured on the soundtracks to the films Shaft (2000) and Dr. Dolittle 2 (2001), respectively. Keys' first studio album Songs in A Minor was released in June 2001. Musically, it incorporated classical piano in an R&B, soul and jazz album. Jane Stevenson of Jam! described the music as "old-school urban sounds and attitude set against a backdrop of classical piano and sweet, warm vocals". USA Today's Steve Jones wrote that Keys "taps into the blues, soul, jazz and even classical music to propel haunting melodies and hard-driving funk". Debuting at number one on the Billboard 200 with first-week sales of 236,000 units, it went on to sell over 6.2 million copies in the United States and 12 million copies internationally. Additionally, it was certified six times Platinum by the Recording Industry Association of America. Songs in A Minor established Keys' popularity both inside and outside of the United States where she became the best-selling new artist and R&B artist of the year.  The album's release was preceded by the April release of her debut single, "Fallin'", which spent six weeks atop the Billboard Hot 100. The album's second single, "A Woman's Worth", was released in February 2002 and peaked at seven on the Hot 100 and number three on Billboard's Hot R&B/Hip-Hop Songs; becoming her second top ten single on both charts. Released in June, "How Come You Don't Call Me" served as the album's third single, peaking at 59 on the Hot 100. The album's fourth single "Girlfriend" was released in the United Kingdom where it peaked at 82. The following year, the album was reissued as Remixed & Unplugged in A Minor, which included eight remixes and seven unplugged versions of the songs from the original.  Songs in A Minor led Keys to win five awards at the 2002 Grammy Awards: Song of the Year, Best Female R&B Vocal Performance, and Best R&B Song for "Fallin'", Best New Artist, and Best R&B Album; "Fallin'" was also nominated for Record of the Year. Keys became the second female solo artist to win five Grammy Awards in a single night, following Lauryn Hill at the 41st Grammy Awards. That same year, she collaborated with Christina Aguilera for the latter's upcoming album Stripped on a song titled "Impossible", which Keys wrote, co-produced, and provided with background vocals. During the early 2000s, Keys also made small cameos in television series Charmed and American Dreams.
Question: What album did she release during this time?
Answer: Keys' first studio album Songs in A Minor was released in June 2001.

Background: A musical ensemble, also known as a music group or musical group, is a group of people who perform instrumental or vocal music, with the ensemble typically known by a distinct name. Some music ensembles consist solely of instruments, such as the jazz quartet or the orchestra. Some music ensembles consist solely of singers, such as choirs and doo wop groups. In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo (harpsichord and cello) and one or more singers.
Context: Five-piece bands have existed in rock music since the development of the genre. The Beach Boys, The Rolling Stones (until 1993), Aerosmith, Def Leppard, AC/DC, Oasis, Pearl Jam, Guns N' Roses, Radiohead, The Strokes, The Yardbirds, 311 and The Hives are examples of the common vocalist, lead guitar, rhythm guitar, bass, and drums lineup whilst other bands such as Judas Priest have two guitarists who equally share lead and rhythm parts. An alternative to the five-member lineup replaces the rhythm guitarist with a keyboard-synthesizer player (examples being the bands Journey, Elbow, Dream Theater, Genesis, Jethro Tull, The Zombies, The Animals, Bon Jovi, Yes, Fleetwood Mac, Marilyn Manson and Deep Purple, all of which consist of a vocalist, guitarist, bassist, keyboardist, and a drummer) or with a turntablist such as Deftones, Hed PE, Incubus or Limp Bizkit.  Alternatives include a keyboardist, guitarist, drummer, bassist, and saxophonist, such as The Sonics, The Dave Clark 5, and Sam the Sham and the Pharaohs. Another alternative is three guitarists, a bassist and a drummer, such as Foo Fighters, Radiohead, and The Byrds. Some five-person bands feature two guitarists, a keyboardist, a bassist and a drummer, with one or more of these musicians (typically one of the guitarists) handling lead vocals on top of their instrument (examples being Children of Bodom, Styx, Sturm und Drang, Relient K, Ensiferum and the current line up of Status Quo). In some cases, typically in cover bands, one musician plays either rhythm guitar or keyboards, depending on the song (one notable band being Firewind, with Bob Katsionis handling this particular role).  Other times, the vocalist will bring another musical "voice" to the table, most commonly a harmonica or percussion; Mick Jagger, for example, played harmonica and percussion instruments like maracas and tambourine whilst singing at the same time. Keith Relf of the Yardbirds played harmonica frequently, though not often while also singing. Ozzy Osbourne was also known to play the harmonica on some occasions (i.e. "The Wizard" by Black Sabbath). Vocalist Robert Brown of lesser known steampunk band Abney Park plays harmonica, accordion, and darbuka in addition to mandolin. Flutes are also commonly used by vocalists, most notably Ian Anderson of Jethro Tull and Ray Thomas of the Moody Blues, though these are difficult to play while singing at the same time.  A less common lineup is to have lead vocals, two guitarists of varying types and two drummers, e.g. Adam and the Ants.
Question: are there some bands which have musicians singing and playing an instrument at the same time?
