 AIP stands for "Archive International Productions".The first 10 volumes in the Pebbles series had been released by BFD Records of Kookaburra, Australia (most likely a fictitious label name to avoid copyright infringement lawsuits) in 1979–1980 and have been kept in print by AIP for many years.Including those in the companion Highs in the Mid-Sixties series – which concentrated on American regional music scenes – there are over 50 LPs covering some 800 obscure, mostly American "Original Punk Rock" songs recorded in the mid-1960s – primarily known today as the garage rock and psychedelic rock genres – that were previously known only to a handful of collectors.
