Todd Rundgren-Initiation (1975)

This is probably Todd Rundgren's most progressive solo work, considered by many to be a masterpiece of avant-garde rock, offering everything from energetic tracks to astonishing instrumental exercises on keyboards and guitars. Released in 1975, "Initiation" was his sixth album outside of his band Utopia, and on it the guitarist and producer surrounded himself with a wide range of collaborators, including Edgar Winter, Rick Derringer, David Sanborn, Dan Hartman, Rick Marotta, and Roger Powell, among others. With an unusual runtime of nearly 70 minutes, Rundgren managed to fit a repertoire twice as long as almost any other record released at the time onto just one side of the original vinyl. While the album features several songs with a clear conventional rock feel, it also contains many progressive and experimental moments. The heavy tracks "The Death of Rock and Roll" and "Eastern Intrigue" are perhaps the most peculiar among all the conventional ones, contrasting sharply with the pleasant "Real Man" or the extravagant "Born to Synthesize", an a cappella song sung by Todd himself. However, the expansive "Initiation", "Fair Warning", and especially the hallucinatory instrumental suite "A Treatise on Cosmic Fire" are the high points of this surprising recording by the blond guitarist from Pennsylvania.
