The Rock USA Oshkosh lineup will be announced on Z104 at 6 a.m. on Monday, March 4th! While we can't tell you who will be appearing this year (I hate keeping secrets), we can tell you that Rock USA Oshkosh will be 4 days this year. So mark your calendars for July 17-20 and put in for vacation NOW!

Rock USA Oshkosh is also making it more affordable than ever before. You can enjoy all 4 days for less than a half tank of regular unleaded in the Z104 van!!

Listen for a special Z-Factor at 10 Monday morning and for featured Rock USA Oshkosh artists all day! Tune in and check http://www.z104rocks.com for updates!
