6th Street was formerly named Pecan Street under Austin's older naming convention, which had east-west streets named after trees and north-south streets named after Texas rivers (the latter convention remains in place). The area around nearby 4th Street and 6th Street is the heart of the Austin entertainment district. Many bars, clubs, music venues, and shopping destinations are located on E. 6th Street between Congress Avenue and Interstate 35 and many offer live music at one time or another during the week.
