Hmm, according to Wikipedia Voltron is a giant robot with legs from a Japanese anime – an armoured war machine. You will need some good armour also for that music, because the band from Berlin isn`t playing shallow radio rock, which you can already guess by their musical influences like the Melvins, Mastodon, Neurosis and Cult of Luna. You can hear those influences clearly, and so there are several elements from diverse metal genres on the record – rocky, progressive but especially doomy sounds. With song lengths between 5 and 10 minutes there`s a lot of space for experimenting. Metal for advanced listeners!
