One of my favourite ambient artists who I have considered booking for a show in the past isn't a big name, but Bing Satellites - a prolific lo-fi and space ambient project centred on glacial drones and shimmering spheres of sound design, creates big music. Very wide in scope with many pretty elements like piano, guitar and harmonium occasionally dotted through quieter passages, with a lathering of luscious drone to complete each (usually long-form) album dish. This selected release is one of my favourites...from the "Twilight Sessions" catalogue series; volume 5, free to download if you're looking for stocking up on his music on the cheap.
