In 1965 Nagle helped form the San Francisco, California, USA-based Terrazzo Brothers, the R&B act that soon evolved into the Mystery Trend, one of the instigators of the ‘San Franciscan Sound’. With Nagle on keyboards and vocals, they were a popular live attraction, but were overtaken by others, including the Grateful Dead and Jefferson Airplane. In 1967 Nagle formed the Fast Bucks, which included John Blakely. Three years later Nagle was invited to join Blakely in Stoneground, but he refused, opting instead to record Bad Rice, produced by Jack Nitzsche, on which members of Stoneground and Commander Cody’s Lost Planet Airmen joined Ry Cooder. Nagle’s songwriting talents stretched from tough rock songs to tender, sweeping ballads, each of which were enhanced by his dry wit. Over the years he extended his craft, penning scores for horror movies as well as the Tubes’ song ‘Don’t Touch Me There’. In 1978, he formed the Durocs, but this venture folded two years later. Nagle is now a leading ceramic artist.
