OurStage.com has added four new partners to its recently launched Marketplace tool, which aims to help artists book concerts, while allowing music venue talent buyers to browse for new talent on the road.

The new partners are music festivals Noise Pop (San Francisco) and RedGorilla (Austin, Texas), and musicians Matt Nathanson and Kaki King. Noise Pop and RedGorilla will give top-ranked acts on OurStage the opportunity to perform at their respective festivals, while Nathanson and King will use the Marketplace tool to choose artists who will open 10 concerts on their respective fall tours.

Ourstage's Marketplace tool allows bands to sign up for a free electronic press kit, which can be viewed by talent buyers across the country. Concert bookers can also listen to music the artist has uploaded to the Web site, which is ranked by fans who use the site.

Last month, to help launch Marketplace, OurStage teamed up with Live Nation. Under the partnership, Live Nation will allow OurStage users to choose some of the opening acts at Live Nation venues in New England, Denver and San Francisco.

OurStage allows artists to upload music and videos, which are later voted on by fans. Since launching in March 2007, the Web site has partnered such music festivals as Bonnaroo, Bumbershoot, Newport Folk Festival, JVC Jazz Festival Newport and Noise Pop.
