House 1: Joakim Broden and Devin Townsend would be good fun to hang out with. Tuomas Holopainen is a really creepy looking guy and I reckon I'd feel super uncomfortable around him. Dave would be smiling away and lighting up the house with his cheerful demeanor. I'd probably be quite intimidated by Floor Jansen but also completely in awe of her. Hopefully Devin would write some good music and get the best out of her, which would make things awkward with Tuomas. I know fuck all about Abbath.
House 2: Everything I've heard about Geoff Tate is that he's a self-absorbed egomaniac, so I wouldn't be keen on spending lockdown with him. Lars Ulrich probably has the propensity to speak a load of shit and we've all seen from Some Kind of Monster what he's like in tense situations. I don't know what I'd speak to Steve Harris and John Petrucci about but I suspect there would be a lot of music nerding that I'd be unable to follow. As Lamps mentioned, this house is appealing because there are two women. Cristina Scabbia is nice and I'm a big fan of Charlotte Wessels. I'd be more than happy to spend lockdown with her.
House 3: I reckon I would give into temptation and bait Jon Schaffer into speaking some shit. The man is batshit crazy! I don't have much time for Mike Portnoy because of the way he dealt with his resignation from Dream Theater and some of the things he's said since. Like with Floor, I'd probably be totally in awe of Simone Simons and wouldn't have a clue how to speak to her. I don't know much about Myles Kennedy but he seems decent enough and I've shared accomodation and had beer with
@Shadow so living with Papa Emeritus would be fine, but not as vocally pleasing as Simone and Myles. Other than being in Mastodon I know nothing about Brent Hinds.
House 4: I'm not sure I'd enjoy being around the egos of Tarja Turunen and Rob Flynn for too long. Kerry King is probably a bit of a wanker too. Varg is revolting and I'd stay the fuck away from him. Perhaps I could form a clique with Adrian Smith and Matt Barlow. Hopefully Matt would sing a Pathetic Tearjerker Schlager for me and I could nag Adrian about the solo to 'Alexander the Great'.
House 5: I feel that the combination of Bruce Dickinson, KK Downing and Dave Mustaine could become toxic and chaotic. Bruce and Dave might be able to bond over throat cancer but think the three of them are very opinionated and don't really know when to stop talking. The legendary rivalry between Iron Maiden and Judas Priest that KK keeps talking about might cause some problems too, at least for KK anyway. But it is what it is, you know. ACM is hot but I've also heard some very negative things about her personality, although she's vegan so we could share some nice food. I know very little about Till Lindemann and Christopher Bowes is probably a lot of fun, but I don't really like Scottish people so...
House 6: With Rob, Michael and AvG in this house the level of vocal talent would be through the roof. Anneke is super friendly too (I've already met her) so I'd be happy to spend lockdown with her. At least I know Rob wouldn't be trying to interfere there. James LaBrie seems like a decent guy and might be able to learn from the other three and improve his singing a bit. Corey Taylor is probably a bit of a knob and I'm not much of a fan of his vocals. I know nothing about Glenn Danzig, but he and Kiske could do some Elvis duets.
If I were to pick one person from each house it would be Floor Jansen, Charlotte Wessels, Simone Simons, Matt Barlow, Dave Mustaine and Anneke van Giersbergen.
