2004 - Present : Still the Best

Preliminary work started in December 2003 on new album, with producers Death In Vegas at Sawmills Studios in Cornwall (the same place where Oasis had recorded their debut album), originally slated for a September 2004 release to coincide with the Definitely Maybe 10 year anniversary. However, problems loomed ahead, when in January 2004, longtime drummer Alan White, who had played on most of Oasis' material left the band. At the time, his brother Steve White stated on his own website that "the spirit of being in a band was kicked out of him" and he wanted to be with his current girlfriend. In subsequent interviews, Noel seemed to agree, saying that he has nothing against him, but White's problematic personal life was impeding on his professional commitments with Oasis.

Recording sessions continued with Proud Mary drummer Terry Kirkbride, brought in temporarily, who only performed on the second track "Mucky Fingers" of the new release. Zak Starkey - drummer of The Who and son of The Beatles' drummer Ringo Starr - was asked by the band to join them in the sessions and he performed on all of the subsequent world tour, as well as all of the promo videos for the singles. However, as he isn't introduced yet as an official member of the band, he wasn't featured on the album's sleeve and rarely appeared with the rest of them in promotional activities such as interviews and photo-shoots.

In June 2004, Oasis headlined the Glastonbury Festival for the second time in their career, with their new drummer, and performed a greatest hits set which also included two new songs - Gem Archer's "A Bell Will Ring" and Liam's "The Meaning of Soul". The concert received mixed reviews, mostly because Liam was having problems with his singing, which made him quit while singing "Stop Crying Your Heart Out" and Starkey was still getting to grips with the load of songs which he had only played publicly for the first time a couple of days previously.

In September 2004, the band released Definitely Maybe: The DVD commemorating the 10th anniversary of their debut album's release. The DVD contains an enhanced audio version of the album, four hours of live footage, and interviews with band members and the production team.

On 30 May, 2005, after three years and three scrapped recording sessions, the band released their sixth studio album, Don't Believe the Truth, fullfulling their contract with Sony BMG. It followed the path of Heathen Chemistry as being a collaborative project again, rather than a Noel-written album. Also it was the band's first album in a decade not to feature the drumming of Alan White, with Zak Starkey taking his place. The record was generally hailed as the band's best effort since (What's The Story) Morning Glory? by fans and critics alike, spawning 2 UK #1 singles with "Lyla" and "The Importance of Being Idle" (the band's 7th and 8th #1 UK singles, respectively), whilst "Let There Be Love" entered at #2. Oasis picked 2 awards at the Q Awards: one - a special People's Choice Award and the second for Don't Believe The Truth as Best Album. Following in the footsteps of the previous five studio albums, Don't Believe The Truth also entered the UK album charts at #1.

In May 2005, Oasis embarked on a huge world tour. Beginning on 10 May, at the London Astoria, and finishing on 31 March, 2006, when the band played a sold out gig in Mexico City to 17,000 people, Oasis played more live shows than at any time since the Definitely Maybe tour of 1994/1995, visiting 26 countries, headlining 110 shows and playing to 1.7 million people. The tour passed without any major incidents and is the most successful one for the band for more than a decade.

The first confirmed Oasis release of 2006 is a greatest hits double album entitled, Stop the Clocks, which will feature what the band consider to be their "definitive" songs. Noel is believed to disapprove of this; he had previously ruled out a "Best of" album collection, stating that he didn't want to release one until the band had split. Another 2006 release will come in the form of "Lord Don't Slow Me Down", a rockumentary film looking back at the mammoth 2005-2006 Don't Believe the Truth world tour.

In September 2006, Noel Gallagher stated that due to promotional work and the after-effects of Stop the Clocks, and the fact that they still haven't signed a new recording contract, no work on their next album is planned until at least the middle of 2007. Also a factor in this delay is that Zak Starkey, whom Noel wants in the band and on their next album, is on tour with The Who until around June 2007. Gallagher also confirmed that the band have "loads and loads" of material written for Don't Believe the Truth. Gallagher has claimed that, out of that material, they have enough to make an album equivalent in quality to Don't Believe The Truth.
