In June 1973, Transatlantic released Gryphon's self-titled debut album, recorded in engineer Adam Skeaping's attic. It marked an early expansion to their sound with the addition of electric guitars, keyboards, and various wind instruments such as the bassoon and krumhorn that were featured little in rock music at the time. The group developed a live reputation in folk and rock clubs across the country; their early period included performances at Shakespeare celebrations at St. Paul's and Southwark Cathedrals. Gryphon received nationwide exposure soon after with features on all four BBC Radio stations within a five-day period. Later that year they composed for the documentary film "Glastonbury Fayre" (1972) and completed a European tour. By 1974, Gryphon acquired Phillip Nestor as their new bassist.
