Problem: Led Zeppelin is the eponymous debut studio album by English rock band Led Zeppelin. It was first released on 12 January 1969 in the United States and on 31 March 1969 in the United Kingdom by Atlantic Records. Featuring integral contributions from each of the group's four members, the album was recorded in October 1968 at Olympic Studios in London, and established their fusion style of both blues and rock music. It also attracted a large and devoted following to the band; Zeppelin's take on the emerging hard rock sound endeared them to parts of the counterculture on both sides of the Atlantic Ocean.

In a 1990 interview, Page said that the album took only about 36 hours of studio time (over a span of a few weeks) to create (including mixing), adding that he knew this because of the amount charged on the studio bill. One of the primary reasons for the short recording time was that the material selected for the album had been well-rehearsed and pre-arranged by the band on Led Zeppelin's tour of Scandinavia in September 1968. As Page explained, "[the band] had begun developing the arrangements on the Scandinavian tour and I knew what sound I was looking for. It just came together incredibly quickly." In addition, since the band had not yet signed their deal with Atlantic Records, Page and Zeppelin's manager Peter Grant paid for the sessions entirely themselves, meaning there was no record company money to waste on excessive studio time. In another interview, Page revealed that the self-funding was to ensure artistic freedom: "I wanted artistic control in a vise grip, because I knew exactly what I wanted to do with these fellows. In fact, I financed and completely recorded the first album before going to Atlantic ... It wasn't your typical story where you get an advance to make an album - we arrived at Atlantic with tapes in hand ... Atlantic's reaction was very positive - I mean they signed us, didn't they?" The group reportedly recorded their songs for PS1,782. Led Zeppelin archivist Dave Lewis noted that "[w]ith the possible exception of the 12 hours that the Beatles took to record their first album at Abbey Road, rarely has studio time been used so economically. Led Zeppelin's debut album went on to gross more than PS3.5 million, just short of 2,000 times more than they invested!" For the recordings, Page played a psychedelically painted Fender Telecaster, a gift from Jeff Beck after Page recommended his boyhood friend to the Yardbirds in 1965 as a potential replacement for Eric Clapton on lead guitar. This was a different guitar from those he favoured for later albums (most notably a Gibson Les Paul). Page played the Telecaster through a Supro amplifier. He also used a Gibson J-200, borrowed from Big Jim Sullivan, for the album's acoustic tracks. For "Your Time Is Gonna Come" he used an out-of-tune Fender 10-string steel guitar. Two other songs from the sessions, "Baby Come on Home" and "Sugar Mama" both appeared on the 2015 Coda reissue (although "Baby Come on Home" was first released on the 1993 compilation Boxed Set 2.)

Why did it only take 36 hours?

Problem: Crowded House are a rock band formed in Melbourne, Australia, in 1985. The founding members were New Zealander Neil Finn (vocalist, guitarist, primary songwriter) and Australians Paul Hester (drums) and Nick Seymour (bass). Later band members included Neil Finn's brother, Tim Finn, and Americans Mark Hart and Matt Sherrod. Originally active from 1985 to 1996, the band had consistent commercial and critical success in Australia and New Zealand and international chart success in two phases, beginning with their self-titled debut album, which reached number twelve on the US Album Chart in 1987 and provided the Top Ten hits

In 2006 Neil Finn asked Nick Seymour to play bass on his third solo album. Seymour agreed and the two joined up with producer and multi-instrumentalist Ethan Johns to begin recording. As the recording sessions progressed it was decided that the album would be issued under the Crowded House band name, rather than as a Neil Finn solo album. In January 2007, the group publicly announced their reformation and on 23 February, after 20 days of auditions, former Beck drummer Matt Sherrod joined Finn, Seymour and Mark Hart to complete the new line up. As Sherrod and Hart had not participated in the initial sessions, four new tracks were recorded with producer Steve Lillywhite including the album's first single "Don't Stop Now". On 17 March 2007 the band played a live show at their rehearsal studio in front of around fifty fans, friends and family. The performance was streamed live as a webcast. The two-and-a-half-hour set included some new tracks, including "Silent House" co-written by Finn with the Dixie Chicks. A concert onboard The Thekla, moored in Bristol, followed on 19 March. Crowded House played at the Marquee Theatre in Tempe, Arizona on 26 April as a warm-up for their appearance at the Coachella Festival on 29 April in Indio, California. They also played at the Australian Live Earth concert in Sydney on 7 July. The next day, Finn and Seymour were interviewed on Rove Live and the band, with Hart and Sherrod, performed "Don't Stop Now" to promote the new album, which was titled Time on Earth. The single was a minor hit in Australia and the UK. The album was released worldwide in June and July. It topped the album chart in New Zealand and made number 2 in Australia and number 3 in the UK. On 6 December 2008 Crowded House played the Homebake festival in Sydney, with warm up gigs at small venues in Hobart, Melbourne and Sydney. For these shows the band were augmented by multi-instrumentalist Don McGlashan and Neil's younger son, Elroy Finn, on guitar. On 14 March 2009 the band joined Neil's older son, Liam Finn, on stage for three songs at the Sound Relief concert in Melbourne.
