Tall Cotton String Band is an Oklahoma City-based bluegrass band that blends traditional bluegrass with newgrass and a little bit of that old-time ragtime and swing. TCSB takes the form of a four-piece bluegrass band: banjo, mandolin, guitar, and upright bass. They play in bars or under the stars. Their alter-ego, The B-Team can often be seen on the streets of Oklahom City or Dallas on a Guerilla Bluegrass srike.
