Thousands of metal fans are due to descend on Birmingham on Saturday 5th July, as Black Sabbath hosts its Back To The Beginning concert.
Held at Villa Park, the gig features dozens of huge names from the industry performing across the day.
Perhaps the most exciting part - Black Sabbath with reunite to perform, and Ozzy Osbourne will take to the stage for the final time for his own set.
Here is everything you need to know if you are attending the concert:
West Midlands Railway said it would run an additional 12 services to/from Whitton station on the day of the event.
There will be four additional services in the morning, and eight in the evening after the concert has finished.
The company's normal timetable will be in place for Aston station.
Aston Villa will provide a regular shuttle bus service before and after the event.
Before the concert, shuttle services will run from Dudley Street, departing in 10 minute intervals.
Fans will be dropped off at Aston Hall, over the road from Villa Park.
After the gig, shuttles will run from Aston Hall to Dudley Street every 10 minutes, with the final bus leaving at midnight.
Tickets can be purchased on its dedicated parking website, and can be bought on the day at either end of the service.
Fan travelling by train can use either Aston or Witton stations, which are walking distance from the venues.
West Midlands Railway said Witton is slightly closer to Villa Park, so is more suitable for fans with accessibility requirements, or who may struggle walking.
Both stations have connections to Birmingham New Street.
A taxi rank will be operating at Aston Parish Church, adjacent to the stadium.
Bus services that serve Villa Park are the 7, 11A and 11C. Fans must get off at Witton Square.
As well as this, services 65 and 67 operate close to the stadium where passengers get off at Aston Railway Station.

Aston Villa's website has specific advice for those driving, including where you should exit off nearby motorways.
Fans are not able to park at the stadium, however there are parking sites within a 45-minute walking distance of the venue.
Once they are filled, the next alternative is to park in the city centre, and use public transport to get to the stadium.
