Jerome Froese joins Edgar Froese and Paul Haslinger for another intense foray into the world of electronic music.  Up-tempo tracks such as "Melrose", "Yucatan" and "Rolling Down Cahuenga" predominate, fiery, percussive and minor in tone with structures that build and stirring percussive beats that drive ever-forward.  The interspersed slower tracks are a nice compliment to all of this, gentle and really very pretty (especially the wistful closing selection, "Cool at Heart").  Saxophonist Hubert Waldner, who also played on the group's previous release, "Lily on the Beach", joins the core trio here as well, wailing away to great effect on the opening track.  What I like about Tangerine Dream's work is that it is unapologetically electronic, making full use of synthesizers by playing to their strengths--variety, volume and modernity--rather than trying to use the keyboards to emulate the sound of, say, string orchestras or folk instruments (which they really can't match ...yet...).  By taking this approach, Tangerine Dream creates vibrant, new music--richly textured, intelligently structured, and all their own.  Try their next release, "Tyger" for some creative departures.
