Fast and the furious pony version.
Krystal "Dashie" Dash learns a very big lesson when her parents have a horrible incident proves fatal for them. Now with pain in her heart and revenge on her mind she meets a strange pair and learn a very big secret.

My little work for TwilightClopple birthday and so in my wierd mind set created this.

Fluttershy and Rainbow Dash get tickets to the performance of the new rock band D.S.S that's been taking Equestria by storm. How could they have known that they would meet some pretty interesting ponies, and what would happen next? Out ponies experience everything from singing clowns to the Bells of Canterlot and everything in between. How do two ponies go from fan and the bring-along, to lovers of major artists and to make everything that much more crazy, a night guard captain is hot on their heels!!
Fluttershy and Rainbow Dash are in for an exciting, passion-filled adventure across Equestria... and you get to come along for the ride!

Four friends, with the help of a certain spirit of chaos, are transported into Equestria. With no known way to get back they make a few friends and have a few adventures while they figure out what to do. How will Equestria deal with humans in pony body's, mind you, is an entirely different matter.
