Just like we are unsure of what is going, so are the fans at Helmet. This is what someone posted on the forum:
"As far as other recent rumours, we have come very close to official confirmation that Frank Bello is out and Jeremy Chatelain is the new bassist for good (most recently supported by the apparent statement by Page at a recent show that Jeremy "will be my bassist until death", or something like that). We also got confirmation from Chris and Page that Chris is still in the band, just not on this tour because of Institute. Page has also mentioned going into the studio early next year to work on a new album, which would presumably be him, Chris, Jeremy, and John T."
Jeremy is the guy who was filling in for Frank, thus the reference to the "replacement" bass player. I guess we will find out soon enough. When I asked Scott in the chat, he said that he felt that Frank was here to stay. Frank is one of my favorite musicians and I will support whatever he does, but I really hope he stays where he belongs in Anthrax.
