Thus far in the 21st century, Parlophone has topped both charts simultaneously three times - the first twice (in 2001) when Kylie Minogue's Can't Get You Out Of My Head topped the singles survey while parent album Fever ruled the album roost.
In 2008, Coldplay did likewise with the single Viva La Vida and the album Viva La Vida Or Death & All His Friends sharing the glory for a week.
Plastic Beach sold 74,432 copies in the week to debut at number two, compared to the 105,320 copies Gorillaz' last regular album, Demon Days, sold when debuting at number one in 2005 on its way to overall sales of 1,703,308. Their self-titled 2001 debut opened and peaked at number three, with first-week sales of 47,903, which have since grown to 885,324.
Returning to the top of the albums chart for the first time since 1999 is a bittersweet achievement for Boyzone. Their first regular album for 12 years is also their first since the death of Stephen Gately, whose passing is alluded to in its title, Brother.
Its release tied in with their UK tour, the album sold 101,096 copies last week - the highest weekly tally by any album in 2010 - and follows the number nine success of introductory single, Gave It All Away.
To reach number one, Brother also had to fight off the challenge of Amy MacDonald's follow-up to her chart-topping debut, and the original cast album for Andrew Lloyd Webber's new musical. Boyzone's Ronan Keating also topped the Mother's Day last year, when his Songs For My Mother - dedicated to his mother, Marie - was number one.
Scottish singer/songwriter MacDonald's debut disc, This Is The Life, entered the chart at number two in July 2007 (29,390 sales). It reached number one 23 weeks later, and has sold 762,761 copies to date. New album A Curious Thing debuts at number four (42,372 sales).
Andrew Lloyd Webber's new musical Love Never Dies had had very mixed reviews but the original cast album debuts at number 10 on sales of 31,113 copies. It's the sequel to Lloyd Webber's magnum opus The Phantom Of The Opera, which completed a three week run at number one 23 years ago this very week.
With so many eagerly awaited albums making their debuts, last week's top titles are scattered - Alicia Keys' The Element Of Freedom weathers the storm best, holding at number three (55,192 sales), followed by Lady GaGa's The Fame (2-5, 41,423 sales).
The Glee Cast album is caught up in the slump too, dipping 4-9 (33,411 sales) but by far the biggest loser is Ellie Goulding. Her debut album Lights topped the chart last week - now it dives to number 16 (19,398 sales).
It's the second biggest fall from number one ever, behind the 1-18 dive of George Harrison's All Things Must Pass in 1971, though Harrison's slump came at the end of an eight week residency at number one, and was partially due to disruption caused by a postal strike. The previous biggest fall by a female solo artist was the 1-9 decline of Dido's No Angel in 2001. Goulding's crash comes despite introductory hit Starry Eyed spending a third week at number four on the singles tally (39,942 sales).
Jimi Hendrix's first six chart albums came in the last three years of his life - and since he died in 1970 a further 24 Hendrix albums have joined the tally, with the latest, Valleys Of Neptune, debuting at number 21 this week (14,521 sales). Perhaps surprisingly, it marks Hendrix's first appearance in the albums chart at all since 2002.
With 13 chart singles under his belt, Lemar's earned a right to release a compilation, and Hits debuts this week at number 18 (18,527 sales). Four regular albums released by Lemar have sold more than 1.7m copies.
Lemar's album was one of many that likely benefitted from marketing as a Mother's Day gift. Others enjoying an uplift included Michael Buble's Crazy Love (climbing 14-6, with sales up 204.4% at 40,490), Andre Reiu's Forever Vienna (falling 10-11, but with sales up 90.1% at 29,769), Simply Red's Songs Of Love (25-12, 198.4%, 26,093 sales), Susan Boyle's I Dreamed A Dream (34-26, 88.3%, 13,509 sales) and Matt Monro's The Greatest (40-28, 94.4%, 11,528 sales).
Albums aimed at the Mother's Day market dominate the compilation chart, where Forever Friends: Mum In A Million jumps 10-1 (26,771 sales).
Overall, album sales improved by 34.4% week-on-week to 2,590,338. In the week immediately prior to Mother's Day in 2007, when it fell on 18 March, 2,939,079 albums were sold. In 2008 (3 March), that figure dipped to 2,747,167, and last year (22 March) it was 2,422,144.
Tinie Tempah's Pass Out prevails again on the singles chart, with second-week sales of 64,573, easily enough to see off Rihanna's Rude Boy, which holds at number two (51,543 sales).
Highest debut honours go to Justin Bieber. The 16 year old Canadian, who reached number 11 with debut hit One Time in January, is joined by rapper Ludacris on Baby, which debuts at number three (45,805 sales).
Singles sales are off 9.09% week-on-week at 2,654,753 - 3.92% below same week 2009 sales of 2,763,168.
