Joining the Jayhawks in 1996, Greene played violin on Sound of Lies and Rainy Day Music, and performed live off and on with the band. A phenomenally busy violinist, Greene has performed with myriad local bands, put out a solo album in 2006, and has since joined the Foo Fighters on tour and relocated to Los Angeles.
Johnson also joined the group in '96, along with Greene. Both are members of "super group" Golden Smog (along with Dan Murphy of Soul Asylum, Jeff Tweedy of Wilco, the Jayhawks' Gary Louris and Marc Perlman, and a rotating cast of guests). Johnson has also played in local groups Run Westy Run and Iffy. He is now performing as a solo artist under his full name, Kraig Jarrett Johnson.
Aside from Louris, Perlman is the only Jayhawks member who was active in the group for its entire career. In addition to his work in the Jayhawks and Golden Smog, Perlman has recently started playing his own songs in the acoustic duo Janey & Marc, along with former Astronaut Wife lead singer Janey Winterbauer. Their debut album, 25:32:47, was released earlier this year.
O'Reagan played drums with the Jayhawks from 1994 until the band went on hiatus, and he still plays with the band at reunion shows. Now a solo artist, O'Reagan released a critically acclaimed, self-titled debut album in 2007 and still plays sporadically around the Twin Cities.
Drummer Callahan played with the band from 1988 through 1993 and left following the recording of Hollywood Town Hall. He is now a furniture maker in Milwaukee.
After playing keyboards in the group from '92 to '98, Grotberg left to raise her baby daughter and focus on her family. She still occasionally appears at Jayhawks reunions.
After drumming with the Jayhawks in the '80s, Spencer left in 1988 and founded music house Asche & Spencer. Based out of both Minneapolis and Los Angeles, Spencer's highly successful company composes scores for television and movies.
