From The Treniers' All Music Guide Biography:
Featuring twin brothers Cliff and Claude Trenier, the Treniers helped link swing music to rock & roll with their brand of hot jump blues in the late '40s and early '50s. To the latter-day listener, their early-'50s singles sound closer to swing than rock; indeed, Cliff and Claude had once sung with the Jimmie Lunceford Orchestra. The group did anticipate some crucial elements of rock & roll, though, with their solid, thumping beats, their squealing saxophone solos, and their song titles, such as Rocking on Sunday Night, Rockin' Is Our Business, and It Rocks! It Rolls! It Swings!. The Treniers' brand of swing-cum-R&B was undoubtedly an influence on Bill Haley, who saw them when both acts were playing summer shows in Wildwood, NJ. They had work recorded for OKeh in the early '50s; by the middle of the decade, their sound was more R&B-oriented. Like many early R&B pioneers, they were unable to find success in the rock & roll era, though they appeared in a few of the first rock & roll films.
