这个具有全球化思想诱惑力的演出团体的名称来源一个数学术语，借此表达了他们对某一主题做即兴（音乐）表演的愿望，即使对于那些极具传统因素的歌曲形式也不例外。为了保留乐队的波斯传统风格，他们在把来源于其他文化中的音乐融合在一起的时候，通常都会在其中植入波斯乐，这也使得那些不同地域的人都能易于接受。乐队由创始人——吉它手兼diwan演奏手Loga Ramin Torkian领军，他们那具有锐意创造性的声音包括有四分吉它，（拨弦乐器）saz ，diwan（中东的一种琵琶），亚美尼亚的duduk（一种双簧管），竖笛，电提琴，以及其他一些来源于世界各地区的打击乐器。本张专辑的亮点在于它的独创性，以及用Raga（印度、巴基斯坦音乐中的一种）调式对奥玛开阳（波斯诗人及天文学家）的召唤诗歌的动人阐释，而且专辑中的许多曲子都一一对应着诗歌中的某一诗句。对应《Mystics and Fools》这首曲子的诗歌讲述的是“沉醉于美酒之中”，给人的感觉是迷幻而轻快的一种精神状态——听上去像是用竖笛、diwan，和吵闹的打击乐器编织出的一首适合欢快起舞的眷群音乐。《Evanescent》的特色是像一首充满冥想的诗，因此显得较为神秘、氛围感（有人甚至认为Torkian就是在弹奏“氛围吉它”）。《Parting Ways With the Soul》体现的是Mamak Khadem在一段忧郁的声学贝斯和大提琴旋律中的深情演唱。整张专辑就是在这种忧郁沉思与狂喜张扬之间变化多端的演绎 　　 　　by Jonathan Widran 　　The name of this provocative global-minded ensemble comes from a mathematical term which helps define their desire to improvise on a theme, even within the parameters of traditional song form. While remaining true to their Persian roots, they incorporate the sounds of other cultures, with the end result being to make Persian music more accessible to people from foreign cultures. Led by founding guitarist and diwan player Loga Ramin Torkian, their progressive sound incorporates the quarter-tone guitar, saz, diwan (Middle Eastern lutes), the Armenian duduk (oboe), clarinet, electric cello, and other global percussion instruments. The focus here is creating unique and seductive interpretations of Raga Omar Khayyam's evocative poetry, and most of the tracks here have corresponding passages in the liner notes. The passage for "Mystics and Fools" talks about being drunk on precious wine, and there is a trippy, lighthearted spirit about the song as well -- it sounds like joyful and danceable harem music driven by clarinet, diwan, and jangling percussion. "Evanescent" features a more contemplative verse, and thus is more mystical and ambient (Torkian is even credited as playing the "ambient guitar"). "Parting Ways With the Soul" features Mamak Khadem's passionate-plea vocals over a moody acoustic bass and cello line. The tone throughout varies between this kind of melancholy contemplation and rapturous expressions of frenetic joy.
