I am talking to Toumani Diabaté on a phone line into Bamako that, as he explains with an audible shrug, sometimes works and sometimes doesn’t. He was due in London a couple of weeks ago to promote Ali & Toumani, his album of duets with the late, great Malian guitarist Ali Farka Touré, but was struck down with malaria at the eleventh hour. It rather puts the standard rock star bleating about "stress and exhaustion" to shame.

On a new CD compilation from Strut Records out this week, Next Stop... Soweto, we’re back in Soweto in the 1960s and 1970s and it's the dark, dark days of apartheid; an era in which it was actually against the law for a black South African to even be a musician, and live music was banned from most public places in black areas. There were also no cinemas, bars, hotels, shopping centres or electricity and death was an everyday fact of life.

Latin Music USA is a long-overdue exploration of the Latino influence on American popular music. The four-part BBC Four Friday-night series zooms in on the bicultural American populations rooted in Cuba, Puerto Rico and Mexico, but living in their original entry points, Miami, New York, LA and the Tex-Mex border. The series examines the lifestyles and politics behind the music and their impact in the US beyond Spanish-speaking neighbourhoods. “Each programme looks and feels different, matching the cultures,” explains the London director, Jeremy Marre. In the early days, the Cubans and Puerto Ricans were absorbed as New Yorkers, but on the West coast the Mexicans were still called "shit-kickers".

Oumou Sangare, Malian diva and one of the world’s great singers, is not, as I eventually found out myself, a woman to be trifled with. When she bought some land outside Bamako, the capital of Mali, a local official by accident or oversight also sold the land to someone else who planted the fields. Sangare turned up with a bulldozer and destroyed the man’s crops. She also had a quiet word with the President of Mali and got the offending official sacked. I could easily imagine Sangare in her preferred garb of traditional colourful African robes and Parisian stilettos in the driving seat of a bulldozer – she’s chic, tough and is a woman who bridges the divide between cosmopolitan and traditional Africa.

“The human body is extremely limited. I would love to upgrade myself” says Kevin Warwick, one of the boffins interviewed on screen in Three Tales, the “video opera” from composer Steve Reich and his partner - they live as well as work together- video artist Beryl Korot, their “meditation on 20th Century technology.” When I met them the morning after the launch party in Amsterdam I could have done with an upgrade myself.

I meet Corinne Bailey Rae upstairs at Ronnie Scott’s in Soho – she wanders into the room and a couple of record company types intercept her. I hear phrases like “consumer segmentation”, “demographics”, “functionality of streaming” floating across the room – it sounds like someone has a new type of iPhone app they want her to sign up to. She looks polite, if a bit bemused. But in a depressed record business, Corinne Bailey Rae is a really big deal.

Last night's BBC Radio 2 Folk Awards ceremony was a surprisingly glitzy affair at the Brewery, near the Barbican in London. Winners included Bellowhead for Best Live Act and Lau for Best Group. Steve Knightley's recession sing-a-along "Arrogance, Ignorance and Greed" won Best Original Song, Cara Dillon won the best album for Hill of Thieves and Martin Simpson won the Best Traditional Song for his version of "Sir Patrick Spens". Sam Carter won the Horizon Award for up-and-coming artist, but one consensus of the evening was that 26 year-old Jackie Oates, who had three nominations in the Folk Awards – for best singer, album and traditional song - is on the verge of becoming a major folk star.

Amongst all the musical benefits for the victims of the Haiti earthquake, one club event which took place on Wednesday night in London stands out as a small, but powerful, beacon of hope. Not because it could rival Jay Z and U2 for levels of funds raised, but because it represented levels of commitment, self-motivation and unity among the capital's multi-ethnic youth subcultures that flies in the face of scare stories about gang violence, drugs, educational failure and all the rest of it. Raising well over £10,000 for Haitians, the entire event on Wednesday night at the club Den/Centro was pulled together in a mere three days by journalist and activist Chantelle Fiddy, promoters SOMEnight, and DJ Stanza of the Watford-based dubstep and grime label True Tiger, and went without hitch despite featuring on its diverse bill many grime rappers and DJs who find it difficult to perform in London due to police pressure on promoters. theartsdesk spoke to a dazed but happy Chantelle Fiddy yesterday to discuss the ramifications of the event.

Nashville is much more than the Grand Ol’ Opry, big hairdos and rhinestones, and I was looking for something beyond the occasionally enjoyable kitsch.
