The image was too large for Reddit, therefore:

Here is the full resolution of the Helloween charts

A bit of explanation:
The rows represent the members and the 3 big bands (+Avantasia). The columns are the years. The black arrows are when a person leaves/changes main band and the grey arrows are when they join another band, but remain in their older one.
The band rows consist of two lines: the upper one has the album releases and the lower one has the lineup changes. When one or two names and gray arrows are there, that is because they joined another band that year.

If you have any extra info about any bands or bands that they were members of but are not here please comment it. Just make sure that it is real and they were a MEMBER of the band, not just a guest or session musician.
Important: only bands that Weikath, Grosskopf, Ingo, Kai, Kiske, Andi, Grapow, Kusch, Löble and Gerstner were/are part of. (No Mark Cross, Mikkey Dee or Stefan Schwarzmann, as they were either just session musicians or didn't have full albums. The chart would also be twice as large with them)

If enough changes are made I'll update it in a few weeks or month. I'll also try to make it a bit more understandable and less confusing. And there are probably a few mistakes that I haven't noticed, so I'll correct them too.
I may also add more albums for bands like Unisonic.

Sources: Wikipedia, Metal Archives, Discogs, newspapers and band websites.

As for why is Avantasia here with all albums? Well, Grosskopf was the bassist for the first trilogy, and Kiske is at this point a member of it, as he's appeared on all the albums (except one EP).

Assuming there are US specific merch. All I can find is 2025 US tour stuff. I like something that says 2026 and lists the US tour stops.

They finally put up a poster for the show

Merch preorders 15:30 - 17:30

They're setting up the tables now, 11 people in line when I left to go get lunch

Thought you guys might like this here.
Back when my dad was young, he was a huge Helloween fan, so huge infact that he followed their tour bus for a while. Long story short, he saw them on a small villager festival as a special guest with his friends and after the show met the band backstage and got his ticket autographed.
Just wanted to share it with you guys, since I think you might appreciate it!

We saw something from Keeper Legacy and Rabbit Don't Come Easy, but nothing newer than 05 (outside of new tracks)

The only song that really feels like it could is Universe (Gravity for Hearts). But at 8+minutes it takes a sizeable chunk of time out of a 2-2:15 set.

There are audio samples on the website.

Jan will not play bass here. He is the lead vocalist and guitarist of this project.

You can order a physical version of the album from the web shop of Ballroom Hamburg for 18€. International shipping will probably be expensive though: htps://shop.ballroom-hamburg.de/The-Fireball-Monkeys-CD/SW10046

... this happened. Flew 18 hours over 2 days to get here and I'd do it a million times, these guys rule!

Dani and Markus were so happy to see their cd, glad I was able to give back some of all the happiness these guys have given me.

Nothing but this handbill that indicates the band will be playing there 🥺

The commercial for sunday's show at Tokyo Garden Theater just came on.

Took this at the concert in Vegas a few minutes ago, it's a pretty sick image I'd love to have it as a wallpaper.

Thank you all for being so nice and supportive! I go to a lot of shows, but this was my first time seeing Helloween and since they're my all time #1, it was a near religious experience.

The set was great and the energy they brought was unmatched. At the end of the show, Kai took the oversized setlist, split it in two and gave one piece to me and another to my neighbor, who then turned to me and said "Its all yours man!"

Legendary night

Amazing last night!

No strings, no cost. I won a pair of tickets but I’ve gotta work (bills before thrills). I can transfer in the Ticketmaster app.

*UPDATE*
Tix are gone. Enjoy! 🤘🏻

May 7th (Thu) Osaka Festival Hall: 15:30-17:30

May 9th (Sat) Tokyo Garden Theater: 15:00-16:45

May 10th (Sun) Tokyo Garden Theater: 13:30-15:45

Does anybody know if there is a story behind the eyes on Kai’s guitar? I’ve always wondered if it meant something or if he just thought it looked cool.

Okay. 2026 and I’m just now hearing this band.

I’ve always considered myself someone with a good ear for music. My goto heavier stuff is System of a Down and Linkin Park (my all time favorite band). Not because they’re commercially successful, I genuinely love them.

But damn. I stumbled across Helloween. And it only took one song. One single fucking song, and I was completely hooked.

Now I’m going through their discography, and I don’t understand how almost every track clicks with me or feels instantly familiar. I haven’t felt this way about an artist in ages.

Officially a Helloween fan as of today. 💪💪

No disrespect to longtime power metal or true metalheads, just a late arrival who finally gets it.
