there are many advantages and disadvantages - me being a mobile Dj i am 100% digital at parties - whether its cds, minidisc, mp3 and video dance parties - i mean no one wants to shell out from $650 - 3,000.00 on a Engagement Party, Wedding or Bar Mitvah and see a guy carry in 10 crates of records and a coffin... on the club end i think you need to go with the technology up until a certain point - i know DJs that bring cds and records to the venue sometimes they spin 100% cd sometimes its varies - premixed cds that are done in the studio should not be used by a club jock for more than just a quick segue into another track a few years back i was with Sal Parm at a club in Brooklyn, - we walked in with 3 cd books - the bouncers were like where are the crates of records - Sal was like no this is all my music - one bouncer was like sure - yeah good luck with that how do you mix cds? - By 4:00am we were leaving and the bouncers said that they couldn't believe that he mixed all that music live from Cds hello your club have dennon's and pioneers set ups for a reason!!!
