Jason was never in Til Tuesday, but Jon Brion was. Jason was in the Three O'Clock and Jellyfish, prior to the Grays. BTW, it's only available in Japan, but I worked on a record with Jason, Roger Manning and Brian Retizell (the drummer from AIR) called TV Eyes. (That's also the name of the band.) You should definitely check that out. It's some amazing New Wave type stuff.
Bedtime with the Beatles was recorded at Ocean Way. Jason has huge balls, as far as I'm concerned: When he worked with McCartney on Paul's last record, he played him both of the Bedtime Records.
Jason's current home studio, last I saw it, was a Soundelux U99 as his main vox mic, an Auditronix console (IIRC), a Urei 1178 and a bunch of other things that I don't remember. He's been working with a PT rig for the last couple years.
I love his demos. What they lack in fidelity, they make up for in everything else. I mastered his covers record and his demos record. Total fucking genius, he is. He;'s one of those guys that I'd work with for free any time he asked, because I'm such a fan of his work, and because we've been friends for so many years.
Regarding The Grays mixes, there was a lot of craziness and I think too much micromanagement by four really talented people who wanted to make the record to end all records. However, I was really disappointed when I heard the final result, as I think were most of the band themselves. JJP threw up a rough mix on the console at studio for me of one track, and it killed me. What I heard on the CD made me wonder what happened to the rough he threw together in five minutes.
The Grays record never managed to capture what made them so great live. They tried everything, too. They even had a bunch of us come and be an audience in the studio for a session they recorded live. I went to all of their showcases and they played my birthday party one year, and they would just wow everybody. Once they made the record, even their live magic was gone. I'm happy that I got to witness those early great shows when they all still got along and there was excitement. Some people think the record is amazing, but perhaps I'm jaded by the fact that I heard them do so much better, and felt like it wasn't the best representation of how great they were.
