Candid rock photos taken by Michael Friedman to be on display at California Heritage Museum

SANTA MONICA, Calif. -- Some previously undeveloped rock 'n' roll images are getting some exposure in Santa Monica.

For more than 45 years, candid black and white photos of rock legends sat in the attic of Michael Friedman. The former music manager and producer took the photos between 1969 and 1973. Now they will be on display at the California Heritage Museum.

ROCK & ROLL LEGENDS: The Lost Negatives of Michael Friedman runs from April 14 to July 15.

Friedman packed away the negatives in 1973, then lost track of them. Last year he found them, and with it, unlocked candid photos of rock 'n' roll legends including The Rolling Stones, Janis Joplin and The Band.

After Santa Monica, the collection is then expected to travel to the Rock & Roll Hall of Fame in Cleveland, where it will be exhibited and then archived in perpetuity as The Michael Friedman Collection.
