Depending on the particular camp and the specific situation of the camp, the function of jazz and jazz-influenced music in the Nazi camp system was extremely variable. On the one hand, it was an essential component of illegal and/or tolerated camp culture; on the other, it was a means of propaganda and distraction for the henchmen of the Nazi regime. In their own field of responsibility, individual SS members hardly bothered themselves about the music guidelines of the regime. And so it came to pass that even the SS- Rottenführer (an SS leader) Pery Broad jammed together with Dutch jazz musicians in the men’s section of Auschwitz-Birkenau. Only through such varying motivations could the scorned jazz 'survive' in, of all places, the Nazi camps.

Standard Temperature.It's not very difficult to understand the evolution of jazz into Swing. Ten years ago this type of music was flourishing, albeit amidst adverse conditions and surrounded by hearty indifference....It is the repetition and monotony of present-day Swing arrangements which bode ill for the future." Downbeat, February 1939, pp. 2–16 Another modern development consists of fusing swing (original, or remixes of classics) with hip hop and house techniques. "Swing house" was particularly popular during the late 1980s and early 1990s. Influences incorporated into it include Louis Jordan and Louis Prima. Electro swing is mainly popular in Europe, and electro swing artists incorporate influences such as tango and Django Reinhardt's gypsy swing. Leading artists include Caravan Palace and Parov Stelar. Both genres are connected with a revival of swing dances, such as the Lindy hop. In November 1939, a group of students from Czechoslovakia founded a vocal octet called the Sing Sing Boys in Sachsenhausen. One part of their programme consisted of well-known musical dance numbers of film melodies in a swing arrangement. Beyond that, they used compositions in the jazz idiom from their musical leader Karel Štancl as well as satirical songs from the Liberated Theatre in Prague, which had been closed in 1938 due to its antifascist leanings. These songs contained the heavily jazz-influenced melodies of Jaroslav Jezek, and their performance was prohibited by the German occupiers. Josef Sárka described the concerts of the Sing Sing Boys in a letter:

Roof fans provide a simple way to ventilate large areas and can be used with ducting or without. Typically, axial fans are used without and provide higher volumes, whilst centrifugal fans are used with ducting and can generate higher pressures to accommodate the ducting.

Because the musicians were useful for them, the camp band did offer the possibility of escaping the gas chamber. Later, the remaining musicians were transferred via Berlin and Sachsenhausen into a satellite camp of Dachau. But only a few members of the Ghetto-Swingers survived the Shoah. ConclusionWhen he played, everything became quiet. He magically produced the sound of an entire band. […] Everywhere where Pechmann went, he reassured these frightened people. Kuna, M., 1993.

A roof fan is either an axial fan or centrifugal blower contained within a roof mounted unit that can cover a variety of applications depending upon the design of the unit. Roof fans also come in either vertical or horizontal discharge configuration. But precautions had to be taken so that the performance of hated jazz melodies was not accidentally discovered by an overseer: 'Sometimes at night, after lights out, we were quite precocious and would cover the windows with our bed sheets and then we would sing.'
