Jorn's voice is extremely virsatile. He has an extremely powerful element to it that is controlled, in your face when he wants it to be, as well as a nice focused tone without strain and a very nice pitch to it. I definitely envy the way he can control his voice/range.
Allen/Lande - The Battle features both Russell Allen and Jorn Lande taking turns being the lead vocalist throughout the album, with the other supporting in haromony roles. Easy, catchy guitar riffs makes this album and easy listen, with 2 talented metal melodic singers doing their thing.
