AB still keeps a watchful eye on the annual ‘BBC Sound of...’ listing. Feel free to call it the most influential listing to act as a barometer of artists on the verge of a (global) breakthrough. Last year it was Michael Kiwanuka, and this year California's Haim, who emerged as ’winner’. So that's more than enough reason to convince AB and get them over to Brussels.

Haim – the three sisters Danielle, Este and Alana Haim – are currently scoring very well on the radio with their infectious single ‘The Wire’ and also previously with ‘Don’t Save Me’. Doing so on pretty much every sort of radio station too. Musically, they're still most compared to Fleetwood Mac with a considerable portion of contemporary R&B. The Guardian already praised their first visit to English soil with a raving *****-review. A BBC journalist described them as “Brilliant musicians with a great talent for melodies that shoot right into the 21st century straight out of classic song structures.”

If you're still in any doubt: the winners of the BBC Sound of.. listing in recent years were, aside from Michael Kiwanuka, also Adele, Keane, 50 Cent and Ellie Goulding. In other words, not exactly bad company for Haim to hang out in.

Support for the sold out Haim concert will be Canadian resident of Berlin Sway Clark II. “Frank Ocean meets Lorde” we rightly read somewhere. Which results in a mix of soul with contemporary R&B. Maybe you already know him from ‘Tears Run Dry’, the single by UK-rapper Tinie Tempah
