Blueprint is the fourth album by Irish guitarist Rory Gallagher, released as a vinyl record in 1973. While recording, Gallagher included a keyboardist – Lou Martin to the lineup for the first time.
The album title and artwork were taken from the blueprint of a Stramp “Power Baby” amplifier that had been custom-designed for Gallagher in Hamburg. “It was compact enough to fit into the small luggage compartment of a Volkswagen Beetle” recalled Gallagher’s brother and manager Donal.
