Justin Adams is considered to be one of the UK’s most original guitarists and record producers and is an extremely versatile collaborator. He was brought up in the Middle East - his father was a British diplomat in Jordan and Egypt - and his music is very strongly influenced by his early exposure to Arab culture, in addition to African music, blues, dub and psychedelia. 

"I wanted to do an album that would be very uplifting and positive, as well as inspirational," quoth the divine Miss P of her latest waxing. Starting as she means to go on, she opens with the chunky honky-tonk pop of "In the Meantime", which crams a panorama of hopes and fears behind its perky exterior. We shouldn't worry about nuclear war and Armageddon, she advises, because "nobody knows when the end is coming" and besides, "God still lives in the hearts of men". Oh, and we should take care to look after the planet, too.

No real surprises on John Hiatt's 20th album, except that he can still find ways to put together a fresh, punchy set of songs using much the same ingredients as he's been using for the past 40 years. The songs, as ever, are rooted in rock, blues, country, Southern soul and old-fashioned R&B, though producer Kevin Shirley (Aerosmith, Iron Maiden, Joe Bonamassa etc) has brought focus and weight to the sound.

Bobby Bland had waited through three difficult years, recording for three different labels with no hits and not much to show for it. He had waited through more than two boring years in the Army with no more than an honorable discharge and a bus ticket to Houston. And he had waited still another two years, practising, performing - persevering more than anything - before finally recording a hit record. But now, it seemed, they were coming fast and furious. Bobby had prevailed and his dream had finally come true. He was at last a star.

The Killer B’s have been heralded as a kind of alternative supergroup (their line-up consisting of ex-members of The Screaming Blue Messiahs, Chicken Legs Weaver and The Men They Couldn’t Hang) so my expectations last night were high. But a poor sound system, in conjunction with the band’s desire to play much too loud for that poor sound system, ended up making it very hard to judge whether I was hearing the future of rock’n’roll or just another pub rock band.

Well, there's a nice surprise. Jill Scott was feared lost to music industry machinations, more likely to succeed in her acting career than make a fourth album (she's probably best known now to mainstream British audiences as Mma Ramotswe in The No 1 Ladies' Detective Agency TV series). But it seems a four-year musical hiatus and change of label has done her the power of good, as this is the Philadelphia singer and spoken-word artist's best album since her debut Who is Jill Scott?

Seasick Steve Wold (b 1941) has achieved widespread popularity over the last five years with his raw, rootsy, blues-flavoured sounds. He's also renowned for his customised guitars, such as one featured on his new album, You Can't Teach an Old Dog New Tricks, that's made from Morris Minor hubcaps, and for his stage patter which combines US Southern charm with hobo lore and anecdotes.

A guitar with one string? There is indeed such a thing. It’s played by Seasick Steve, and it consists of a stubby plank of wood, a pick-up and a couple of nails. And a string. The man born 70 years ago as Steven Wold plays it with a slide, and it makes a fabulous, sleazy sound. It’s one of a collection of manky-looking instruments played by Seasick Steve, the former hobo, drifter, session musician and studio engineer who has experienced a late blossoming in popularity as a bluesman and raconteur.

America has been very good to Hugh Laurie. His starring role as Dr Gregory House has shot him to the top of the earnings tree in US television, while comprehensively demolishing existing preconceptions of him as the blissfully idiotic Bertie Wooster, or the half-witted Prince Regent in Blackadder the Third. You might even say that with House, Laurie finally got the chance to play Blackadder.

I've spent the last week feasting on John Martyn via Spotify. He was a gap in my musical education. He turns out, as a large portion of you reading already well know, to be a rich, raw talent. I knew his rep but had a misguided notion he was another blueprint for whiny contemporary singer-songwriters. All that reveals is my own ignorance.
