During the early days of rock music, most songs were recorded specifically to be played on the radio. Radio stations had selected song lengths to be approximately 3 to 4 minutes long. Probably to allow for more advertising and disc jockey talk time and pay for the cost of operating the stations. As a result, many musicians wrote songs to meet this artificial time limit, even though many groups had developed elaborate arrangements that ran up to 6 minutes long. The record companies would electronically shorten the play time cutting out sections they felt would not take away from the basic gist of the song. As a result, many listeners never heard the original recordings of the songs unless they purchased the records or tapes that had, in fact, both the radio version and the original version. In-A-Gadda-Da-Vida was one of those songs.
Iron Butterfly recorded this as a 10 minute string of lyrics, solo drum sections, solo guitar sections and some fade in sections. Unless you purchased the record or listened to some of the more radical FM radio stations, you never heard the original long version.
Pure Air Systems was formed in 1985 and developed a line of HEPA based, fan powered air filtration systems. These systems were designed from all commercial grade components and unlike their plastic housed, cheaply made competitors units, the PAS unit used all steel construction. The PAS units were designed to run for long periods of time ( 10 years plus ) with very minimal maintenance requirements other than just changing the filters on a regular scheduled basis.
The plastic, inexpensive units would operate for a few years, if that, before they had to be replaced. In addition, the cheap units often performed very poorly and made very little difference in the levels of airborne particle reduction resulting in continued respiratory challenges by the users. The PAS units began a new recognition by the public and commercial users that air filtration systems could actually perform as marketed and run for years with the same performance year over year.
As equipment designs and component pieces become simpler and less expensive, the public has been conditioned to built in obsolescence. So if it lasts only a few years, then we aren’t disappointed and just purchase the next one that was designed to replace the broken unit. The engineers and technicians at Pure Air Systems are trying to change that perception by continuing the process of making all of their systems from the best, commercial grade components that give you that extended play just like In-A-Gadda-Da-Vida.
