Rockabilly revivalists Stray Cats strutted into Atlantic City for the first time in 12 years Saturday night and raised the roof of Ocean Casino Resort’s Ovation Hall.

Celebrating four decades as the world’s most-popular exponent of the 1950s genre that blended R&B and country (then considered “hillbilly music” in some precincts) that is one of the DNA building blocks of rock ’n’ roll, the trio came out firing on all cylinders and pretty much stayed in fifth gear throughout the 22-song rave-up.
