is a series of garage rock compilation albums assembled by Tim Warren of Crypt Records, best known for his Back from the Grave series.

The first volume Jump, Jive and Harmonize, was culled from the collection of 45-rpm singles owned by Mike Markesich (colloquially referred to as "Moptop Mike").

[1][5] The series tends to follow the packaging format employed by other garage compilation series such as Pebbles and Back from the Grave: each volume includes detailed liner notes, for this series written by Mike Markesich, which include basic information about each song and group, such as origin and recording date.

[1] The information that they present reflects thorough research, including information about the circumstances of the recordings and brief biographical sketches of the groups.

[1] The various albums in the series occasionally include photographs of groups not actually included on the track listings, sometimes even going as far as to have such bands pictured on the front sleeves.
