Tons of cool ZZ top facts. How about how “Master of sparks” tells the true story[1] of Billy Gibbons and his friend R.K. Bullock who with a workman, welded together a steel ball cage with a seat and seatbelt fitted inside. They placed the cage into the bed of a truck and at night, after reaching a speed of 60 miles per hour (97 km/h), on Highway 6 near Houston (also known as Jack Rabbit Road), rolled the cage out the back with the hapless narrator and friend taking a ride inside. The cage generated a tail of sparks on the road but in its crushed condition stopped rolling. Still moving at high speed, the now egg shaped cage crashed into a fence. Both occupants survived relatively unscathed and were awarded the title “Master of Sparks” by the cheering crowd.
