I like to see: 1. A 3 track CD that looks reasonably pro, (not a tatty, grubby stick on label or worse felt tip pen!) A cardboard wallet is fine as long as some attempt has been made to give it a bit of gloss. A plastic see through wallet is fine too if your CD has been properly printed. Make sure the band name, track list and contact details are on the CD body. All the tracks should be strong, no fillers. Make the first track your best. If you can afford to have your CD mastered, then do so. It's not a good impression if the listener has to turn up his CD player in order to hear your music.CDR is perfectly fine. You need to order a minimum of 500 units to get a CD pressed. If you do this, you need to be sure of selling at least 100-150 to break even. 2. A photo of the band. 10 x 12" B&W is the industry standard, but any decent pic is fine. 3. A single A4 bio stating members, influences, bands played with, venues played. A record label will want to know how many gigs you play a year as well. If you play once every six weeks, a label or promoter will wonder why.Yes I know it's unfair. Personally, I concentrate on the music, but, not all will. If you tour, this is an advantage as you're likely to sell more records. A lot of the time, your stuff will sit in a pile or end up in the bin. This is normal. Nobody does as much A&R anymore. I listen to demos in the car. If a track jumps out while driving, it's a good 'un. Persevere.
