The 1975 Music City USA 420 was a NASCAR Winston Cup Series race that took place on May 10, 1975, at Nashville Speedway in Nashville, Tennessee. Darrell Waltrip won his first NASCAR Cup Series race

Background

Nashville Speedway was converted to a half-mile paved oval in 1957, when it began to be a NASCAR series track. The speedway was lengthened between the 1969 and 1970 seasons. The corners were cut down from 35 degrees to their present 18 degrees in 1972.^{[citation needed]}

Waltrip earned the pole position in qualifying for his fast qualifying run of 103.793 miles per hour (167.039 km/h); driving a 1975 Chevrolet Chevelle Laguna.^[2][3] Only one caution flag waved for a period of eight laps; two changes in first-place were made between Cale Yarborough and Darrell Waltrip.^[2]
