Severed Fifth is the musical alter-ego of Jono Bacon (a name that might be familiar to many Linux users). The album is available from here (various formats), and while it is proper metal, it is also oddly melodic in places. I think if I’d not weaned myself back on to this sort of music with the new Metallica album then I’d hate this. As it is, I think I actually quite like it and would recommend it to anyone who likes their metal fast and loud.
