Mostly Autumn continue to evolve and progress with this, their seventh studio album. They have moved steadily away from their beginnings as a "progressive-folk rock" band towards more main stream "progressive rock", with a good strong dose of the "rock" thrown in from the time of their previous album, 2005's "Storms Over Still Water". That was a brilliant, rocky example of the genre that "Heart Full of Sky" takes still further - the arrangements are more complex than before, with very rich instrumentation, making this an album that rewards frequent repeated listening.
Keyboards player Iain Jennings left after "Storms Over Still Water" to form his own band. However, his departure would not be apparent to the casual listener as the sound continues to be dominated by the song writing talents of Bryan Josh and Heather Findlay, by their shared vocals and by Bryan's strong guitar playing. In essence, this is what makes the Mostly Autumn "sound" and it remains as strong as on their other albums.
Personally, whilst rating both albums as brilliant, I do find "Heart Full of Sky" not quite as good as "Storms Over Still Water": Despite bringing in Chris Johnson as a replacement for Iain Jennings, Bryan has played most of the piano and keyboards himself on this album, one assumes because of the timing issues over Chris`s arrival. Whilst Bryan and Heather are the creative backbone of the band, I sense that Iain did contribute significantly to the synergy of the band by chipping in with ideas for arrangements etc and I think his loss has subtly diminished the final result on "Heart Full of Sky": the arrangements may be more complex than before, but they are not always hitting the bulls-eye. Hopefully for the next album Chris will be fully engaged in the band's creative processes.
Criticising such a fine album is a bit churlish but I am discussing shades of excellence.
There are some excellent songs on here, the pick of them being Chris Johnson's two contributions (auguring well for the band's future) "Blue Light" and "Silver Glass"; Josh's closing number "Dreaming", a rocky song in a number of distinct parts; the beautiful, atmospheric, folk-oriented "Find the Sun"; with top spot for me going to the fantastic "Walk With a Storm", Josh's powerful folk-rocker which begins with angry guitar chords and effective vocal interplay between himself and Heather and ends with a storming passage of frantic uilleann pipes, violin, lead guitar and keyboards.
