I just found this interview from 2008 which is actually pretty interesting. A summary of interesting tidbits...
Lunar Strain wasn't initially intended for any kind of record deal, but Dark Tranquillity made Jesper aware they had been signed by Wrong Again records and suggested he give them a call. Jesper called the label drunk from his parents kitchen and lied about having songs completed to get a record deal
The Jester Race - Johan Larsson was in the military and came back on weekends to record the bass. Anders says that this album and Whoracle are the only concept albums he'll ever do - although I believe ITM was described as a concept album as well.
Whoracle - Glenn Ljungstrom and Johan Larsson were losing interest in the band as they didn't like to travel. Ljungstorm saw no money in the band and Larsson met a girl on the internet and gave up bass as a result
Colony - finding Daniel was important because they found a great drummer and Anders says a big improvement on Bjorn who could "keep a beat but only play, like, one fill". Anders also says "I decided to leave behind all the made-up stories in my lyrics and write about my own mishaps and relationship problems" - which seems like more of a description of Clayman's lyrics than Colony.
Clayman - Anders claims Nordstrom was tired of producing at this point and wasn't that interested in the record, which is strange as Nordstrom has implied the opposite.
Tokyo Showdown sounds like shit and Anders regrets releasing it.
Reroute to Remain - Anders doesn't think the music changed much but that Daniel Bergstrand had a different vision for the band, calls it a "weird time". He calls the response to the album "mass hysteria" and says it was the hardest album for him to record, as Nordstrom let him do whatever he wanted with his vocals, whereas Bergstrand made him do multiple takes to get things right.
STYE - The band were apparently starting to feel divided at this point, which to be honest is news to me. Anders says the band were "surprised" when they started to mix it and felt there were too many keyboards, and not enough melodies or guitar solos. He says he still think STYE sounds good but that there was a lot of arguing and the band needed a break from each other.
Come Clarity was recorded after an Ozzfest tour where the band apparently fought a lot with each other. This resulted in Daniel recording drums on his own, Bjorn/Peter/Jesper recording their instruments together and Anders doing vocals completely separate from all of them. Anders says he likes that there's more guitar than keyboards on Come Clarity but that he feels communication had broken down between the band members. He says he mixed the vocals in without consulting any of the other band members, and just sent them everything when it was done "hoping they would like them."
A Sense of Purpose brought the band back together and they recorded everything in the same studio rather than being separated. Anders says they worked really hard on the sound of the album and everybody had creative input and made an effort to contribute. Which is kind of funny considering CC, the album were they were all apart from each other, turned out way better than ASOP... but whatever.
I have to admit I had no idea the band were so divided during the STYE/CC years.
