US poet and singer Patti Smith helped shape the New York punk scene in the 1970s, making her one of the most influential female musicians alive.

Her new single is out with the album due in the summer.

The Today programme's Nicola Stanbridge spoke to her about punk rock and the evolution of rock and roll.

She said that she did not believe there was any restriction for women in music now and pointed to "unassuming" British singer Adele as being one of the strongest voices in the world right now.
