Thank you for posting this. This really helps highlight the importance of musical guests at Tekkoshocon.
While not everyone may be a fan of a particular band/artist, the fact of the matter is that Tekkoshocon sets itself apart from other conventions by bringing in acts. There are not many venues willing to host foreign bands because there is a lack of following for non-English speaking/performing music. I'm rather sure last year, one or both of the bands made a comment that performing at Tekkoshocon was their absolute largest turn-out while on their American tour. Combine that with the news of the our new record-- it helps us grab the attention of label big-wigs to bring in even bigger performers.
To ask Tekkoshocon to nix the music would be a large step back, especially after breaking a record. Just think about it-- the opportunity to see a Japanese musical artist live is slim to none anywhere else. I have never known any of the bands who have come in the past, but I can definitely say that I've listened to them since they've come to Tekko. Just knowing that I have the chance to see a band that almost no one else will get to see in the country, is exciting. It's an awesome feeling. Showing support helps the show get new, big names in the future-- maybe even some that you've heard of before. It helps labels to want to send more artists to America. If they do, regardless of the band, it helps to create an awareness and following of foreign music. Tekkoshocon is a Japanese Culture Convention. Doesn't every Japanese musical artist fit into that category then? Not just the ones that perform in anime?
