Up until August of 2005, Jon was the only member of Eisley who's not a DuPree. Jonathan Wilson plays bass and looks very cool while doing it. According to his old Eisley.com bio, he speaks fluent German, and he joined the band in 2001 (when they were still MossEisley). He's also in the Tyler Vineyard Church worship band, along with Stacy, Sherri, Kim, and Christie DuPree. Before joining the band, he lived in three different countries and worked with Youth With a Mission until 1999.

Jon was the second-oldest member of the band, at age 22. He left Eisley for personal reasons, but he and the band remain as close friends as ever. Jon has also recorded some solo material that proves his musical talent is not restricted to the bass.
