Meet and greet is the bread and butter of the current climate in music. While DT is one of the absolute most successful band in their genre, they're still mostly doing mid scale shows (2-3000 seaters is the norm rather than the exception). DT is a band who has a pretty extensive apparatus around it so that it can function. Each member has his tech. There's sound and light guys, production managers, tour managers, band managers, tour bookers, and what have you that need to get paid for what they do. Add into this the production costs of staging a show, and the fact that the money from touring is basically all the money the artists are getting (as residuals from royalty checks are pretty darn low nowadays, and most band tour just to reimburse the costs of making an album).
This interview quote from Devin Townsend is interesting (and relevant):
You've always had a good connection with your fans, your meet-and-greets being one example. Your packages have always been reasonably priced, but some people disagree with the idea of meet-and-greets in general; what's your take?
I have two thoughts on the matter and they cancel each other out, so that kinda sucks. The music industry is really difficult. The overhead for me to do this is fucking crazy; we have to pay around $14,000 a month just to function. We didn't tour for a year so I had to come up with fourteen grand a month just to keep everything going, then when we do tour, it's fucking expensive. $1,000 per person to fly shit class from Vancouver, too. A lot of the times, fans may think bands are taking the piss by simply doing a meet-and-greet, but if we don't do them we simply can't do what we're doing. It's not like we do them then get a bonus at the end of the tour.
On the other side of it, if you're in the band and you're hypersensitive to people's energy, like I believe I am, meet-and-greets fucking beat the shit out of you. Not because you don't want to meet people, but because in order to do it correctly, you really have to invest yourself and be present and ready to talk to people and sometimes accept hyperbolic praise or criticism, and you have to be emotionally resilient enough to not let either… I mean, it's about them. They're paying for a moment and your job is to be present and that's really challenging on tour. If you think meet-and-greets are fundamentally stupid then you're never not gonna think that. Some bands are like, "Fuck that, you can come meet me at the bar." I never go to the bar and if I am at the bar, please don't talk to me because I'm there to hang out with my friends. We try to do the best with our packages, but at the same time there's still people who are critical of it.
So basically, the bands need to draw money from any additional sources they can. One way would be to hike the ticket prices (by adjusting the price they charge the promoters for their work). But instead, there's a way to have people contribute what they can - merch and meet and greet packages.
If you decide to go to VIP meet and greet package, think of it first and foremost as a way for you to thank the band. That's my #1 reason to do it for any band I do it with. The service they provide at the meet and greet may be poor or may be great - i've had both experiences. DTs can vary a lot - some cities have like 80 people in the VIP, others may have only 10. Needless to say, the latter is much more relaxed and fun.
As for the whole "who's the best fan" - of course the band appreciates those who pay to meet them, but there's always something special about those who wait outside the bus. They're the hardcore. I think I know who said that thing though
Aftershow passes is a nice private session, but the downside is that theres no guaruantee as to who shows up. Maybe noone shows up. I think most of you can guess in which order of likelyhood there is for certain members to actually show up at these things. And you have to come by someone who actually can give you an aftershow pass. Of attend a fan club event where we're likely to give away a few (i think we gave away something like 50 passes last year)...
TLDR; Musicians need food, buy shit from them so they can eat. Don't go to VIP meet and greet if this isn't your primary reason for doing so.
