For the Global Hit, we are talking about a solar power recording session in the southern Sierra Nevada mountain range, outside Granada, Spain.
It is part of an open air recording project called Wapapura, the brain child of musician Rafa Kotcherha.
And as Kotcherha explains, "for a Wapapura recording to take place, you need three elements: Music, Space and Earth."
"The music is of course the musicians we're going to record," he says.
"The space is the environment in which it is going to take place" and "the earth element is the environmental non-profit, linked to the recording, which benefits from part of the purchase of the CD online when it is released."
