By the late 1960s, many rock bands had begun incorporating instruments from classical and Eastern music, as well as experimenting with
improvisation and lengthier compositions.
East of Eden, for example, used Eastern harmonics and instruments such as a
sumerian saxophone on the album
Mercator Projected in 1969.
[12] Some, such as the UK's
Soft Machine, began to experiment with
blends of rock and jazz. By the end of the decade, other bands, such as
Deep Purple and
The Nice, had also recorded classical-influenced albums with full orchestras:
Concerto for Group and Orchestra and
Five Bridges. This use of classical music would crystallise in the '70s with
Amon Düül II's orchestral score on
Made in Germany (1975), Pink Floyd's
Atom Heart Mother (1970), and several works of
Frank Zappa.

Although many of these bands were from the UK, the genre was growing popular elsewhere in continental Europe.
Triumvirat led Germany's significant progressive rock movement, while
Tangerine Dream,
Faust,
Can and
Neu! led the related
Berlin School and
Krautrock movements.
Italian progressive rock is an important sub-genre led by
PFM,
Le Orme, and
Banco, all of which gained significant international recognition. Other notable Italian bands include
New Trolls,
Area,
Goblin,
Museo Rosenbach,
Il Balletto di Bronzo,
Maxophone and
Locanda Delle Fate.
Focus and
Trace formed in the Netherlands, France produced
