Forget the money: designing record covers is a labour of love, says David Shrigley

Metal band Motorhead have been forced to cancel a number of summer concert dates due the ill health of frontmant Lemmy Kilmister.

Watch the videos below to take in tracks from this week's Playlist.

Best known for his Schubert lieder, tenor Mark Padmore here performs Alec Roth's arrangements of songs and poems for voice and guitar, ranging from a sequence of Thomas Wyatt poems of love lost, to the more reflective, crepuscular tone of modern verses on nocturnal themes by Vikram Seth.

Kveikur finds Sigur Rós in more forceful and declamatory mood than usual, a shift heralded by the explosion that ushers in the heavy guitar riff and juddering bass of “Brennisteinn”.

It's not hard to understand why Nino Machaidze has become something of an overnight sensation since her 2008 breakthrough in Roméo et Juliette at Salzburg. In this selection, the Georgian coloratura soprano combines phrasing of nuanced subtlety with top notes of stunning power, ranging from the lilting, seductive “Quando men vo” from La Bohème to the impassioned gusto of her dramatic Violetta in an extended scene from La Traviata climaxing with a joyous “Sempre libera”.

Since 2007's Era Vulgaris, Josh Homme has undergone both life-threatening medical emergency and life-affirming parenthood, band break-up and superstar collaboration, all of which made recording this follow-up rather fraught – hence the ironic title.

Album of the Week: Singalong anthems with a Sixties beat and lots of swagger

DJ Nick Grimshaw and chart stars Rizzle Kicks have been lined up to host a pair of new music shows for Channel 4.

Hardly wall-to-wall giggles, you might think, but this publicity-shy, TV-shunning, Perrier Award-winning comic’s talent lies in burrowing into the human psyche and dispensing profound nuggets through tales in which, more often than not, he is the hapless protagonist. After The Beginning, Before The End is like a TED talk with added LOLs.

This biography of a great innovator of the past also asks questions about today's technology

Floraleda Sacchi's harp lends itself particularly well to the minimalist logic of Philip Glass's progressions on this anthology of transpositions, never better than on the “Opening” from Glassworks, where the bass pulse beds beautifully among the mirroring figures of the theme.

Chris Kelly was one half of Kris Kross, the kid duo who helped put Atlanta on the hip-hop map with their 1992 worldwide novelty hit "Jump". Known as "Mac Daddy", Kelly and his friend Chris "Daddy Mac" Smith were barely in their teens when the rapper and budding entrepreneur Jermaine Dupri, himself only 18, discovered them in a shopping mall in 1990.

Even if they succeed in beating down the level of costs demanded by the prosecution, Chris Huhne and Vicky Pryce will emerge from prison many thousands of pounds worse off than they were when they went in, and will need to earn money.
