5 oh Trees was a gangsta rap group from Portland, Oregon, produced by Keegan Quinn, with raps by Big Nutz.
Recordings frequently featured vocal contributions from a number of other local underground rappers, including Celebrity Johnson, Bluntman and Dose. The group gets their name from the city's area code, 503.
This group was active from 2003 to 2009. Keegan and Nutz are now working on a new project called Hundred Round Drum.
An early 5 oh Trees demo track, Get Off the Wall, is featured on the 2003 compilation Triple Penetration.
The group's debut full-length album, The Green Hit, was released in 2005; it was made available for download on the Internet, and on CDs sold personally by the artists and their friends. Although the album saw extremely limited commercial success, it has become well respected among Portland independent rap circles.
Over the next few years, many more recordings were made, although plans to continue releasing albums on a regular basis were never realized, and the group was eventually disbanded with the creation of Hundred Round Drum in early 2011.
In December of 2011, 151 Sessions was released, featuring 18 previously unreleased 5 oh Trees tracks.
