It has been a couple of years since the release of CKY's last studio album 'Carver City', even though they released a b-sides/rarities disc earlier this year -- they still had some extra material lying around. The band posted two previously unreleased tracks for download today, listen to them here.

Underground alt-metal favs CKY have released the two new-old songs via their CKY Alliance website. The first of which is and instrumental version of the song '3D', which was recorded specifically for the films 'Jackass 3D' and 'Jackass 3.5'.

The second is also an instrumental track titled 'Step to CKY (Hawaii instrumental version)', a song recorded in Hawaii during the sessions for the band's 2001 album 'Infiltrate-Destroy-Rebuild'. Imagine surf rock meets death metal and you get a pretty clear picture of 'Step to CKY'.

Both tracks will be available as part of the vinyl edition of their 'B-sides & Rarities' album which will be available on CKYAlliance.com soon.
