Released in 1980 by Logo Records, Vardis' debut album, 100 M.P.H., is now considered one of the milestones of the immortal NWOBHM. However, Vardis' roots go back to 1977, when they formed in Wakefield under their original name, Quo Vadis. Now a collector's item, the trio released their first 7" EP, 100 M.P.H., on Redball Records in 1979. In addition to the raw, almost punk-like original versions of "100 M.P.H.," "Blue Rock," "Destiny," and "The World's Insane," 100 M.P.H. '79 Revisited compiles five other early recordings by Vardis. The audio was restored and mastered by Patrick W. Engel at his Temple Of Disharmony in September 2025. The CD version of includes exclusive versions of "Blue Rock," "Dirty Money," and "The World's Insane," recorded at Ohm Studios in July 1978.
