steve choi, formerly of the chinkees, also became a full member playing guitar and keyboards. choi had also played keyboards on the demos that the band made for "progress", but when it came time to record, they decided to have rich zahniser of the hippos play on the album, because at the time he was touring with the band. former jeffries fan club trombonist chris colonnier also played with the band at times in the same role as zahniser. progress was ranked #207 on the greatest albums in 2001.
