Two Toolroom Trax favourites linking up for the first time as Siege and Dario Nunez join forces on their brand new collab 'Heat'. The track was born during a recent writing camp at Toolroom's London studios, where the two producers quickly connected through the same love for big room tech house. The chemistry came naturally, and with UK vocalist I Jah stepping in to lay down an original vocal with his signature UKG and reggae flavour, the record quickly took shape into something special.
