Ottorino Respighi, aside from being one of Italy's leading 20th century composers, was also something of a musicologist, researching and editing ancient music, especially Gregorian Chant. The two works on this interesting Naxos CD are founded on Respighi's research and transcriptions of such early music. Nowadays, transcriptions are rather frowned upon, but these works are perhaps best described as "developments". I think that the pianist Konstantin Scherbakov and his colleagues makes as good a case that can be made for these pieces; they are much less well-known than many of Respighi's symphonic poems
Respighi: Symphonic Poems.
The Concerto in modo Misolidio dates from 1925 and carries a flavour of plainchant throughout. It is a pleasant way to spend a fairly dreamy 35 minutes. The support from the Slovak RSO and Howard Griffiths is very good. The second work, Concerto a cinque, dates from 1933 and is scored for oboe, trumpet, violin, double bass and piano, with strings. It is rather like a Baroque multiple concerto, and is also very nice. Here the band is the highly-regarded Capella Istropolitana under Ewald Danel.
Interestingly, the works were recorded in 1995 and 1996, but were only released in 1999 by Naxos. The sound quality is very fine throughout, as is the playing.
These are some of Respighi's lesser works compared to his tone poems, but they are well-worth hearing and this Naxos CD is most likely the best and most cost-effective way to do so.
