The_Raunchiest_Chudcuddler

So I just found out about this wonderful band Dragonslayer but can't find any info on it. I look it up and it just brings up foreign YouTube videos and there is a small page on encyclopedia metallum. They were originally heavy thunder. Now, here's where I'm confused. The encyclopedia said they broke up, but since 2005 they have been releasing albums in Spanish. I've listened to these albums and they sound extremely similar to the original comp. Album. They have the same singer and everything. Why did they switch to Spanish? What the fuck is going on? I am so goddamn confused and would love help. Thanks! P.s. the song Satan's soldiers by Dragonslayer is superb.
