The Mighty Mighty Bosstones have posted the first two songs from their upcoming rarities collection. Besides rarities, the band recorded three new songs and recently hit the studio with their own bassist Joe Gittleman acting as producer. The record is titled Medium Rare and is due out December 18, 2007.

Though the band's last studio record, A Jackknife To A Swan, was released on SideOneDummy, The Mighty Mighty Bosstones recently announced b–sides and rarities collection will be released on their own Big Rig Records.

The label was formed by the band when they first signed to Mercury Records as an outlet for the vinyl versions of their albums. The major label pressed CDs and cassettes but allowed the band to self–press the vinyl under the imprint. For this collection, the band will apparently be resurrecting the imprint.
