Citing a "period of great change" for both herself and the band, Grace said she doesn't "know how to succinctly explain the reasons behind" Seward rejoining the band after five years away. Read LJG's full announcement via Instagram below.

Against Me!'s 2016 album, Shape Shift With Me, featured Swedish musician Inge Johansson on bass, and he toured with the band following its release. Seward last played on 2010's White Crosses — he was replaced by Johansson in 2013.

Accordingly, Grace stated on Monday that she's "forever thankful for our time playing together" with Johansson, and she wished the bassist "nothing but the best in life." See Against Me!'s upcoming tour dates down after the announcement.

As some people may have noticed there’s been some change happening within @againstme recently and the shows we played in Detroit, Cleveland and Lansing a week ago were Andrew’s first shows back with the band in over 5 years. I don’t really know how to succinctly explain the reasons behind this happening so I’m going to pass on trying. All I want to say is that I love Inge, am forever thankful for our time playing together and what I learned from it and wish him nothing but the best in life. Been going through a period of great change in general lately and this is probably not the last time this year I’m going to have to ask that people be understanding of a choice made, there’s no maliciousness behind my intentions, I just gotta go after what I want. We head back out on tour again last week of July and 1st week of August. Dates in my bio! Photo by @joeleonard
