Karol XVII & MB Valence - Polish representatives of the Deep House and Electronic genre, dedicated to this dance subcategory for over a decade, nominated for Best Deep House Artist Awards on Beatport - the biggest electronic music retailer, awarded by DJ MAG - a monthly DJ magazine as the best Polish DJs. Karol Samocki and Marek Bigajski (as these are the artists' real names), led Loco Records - their independent imprint, to the title of the best Deep House label on Beatport with their three recordings in top 10 best-selling tracks of Beatport's annual sales reports. The pair have been involved in cooperation with many great Deep House artists, starting from Miguel Migs, Brian Tappert, Robert Owens, through Timewriter, Ian Pooley, Jimpster, and ending with Lusine, or Maya Jane Coles. Focusing mainly on releases on their Loco Records label, they also made exceptions and put out their tracks on other smaller or even much larger labels, such as Get Physical, Toolroom, Suara, Armada Deep or Ministry of Sound. Their first original album was released relatively late, because only in 2022, with 3 singers invited to take part in the project: Jono McCleery, Lazarusman and Keely Timlin.
