Electromagnets: Electromagnets. The Electromagnets were a Texas quartet that produced a single album in the mid 1970s. It didn't get a lot of press at the time, but it became sought after many years later due to the rise to fame of guitarist Eric Johnson. It was released on CD in 1998. Musically it draws a lot from fusion, but it reminds me a lot of Canterbury prog, in a lot of places. The players (all of whom have played with Johnson in the recent past) are top notch.
