Rock music seems to be coming full circle back to a singles format like in the early days of rock and roll as singles to download become more prevalent in the computer age thru myspace and other sites. Way back when shows would have several singers on the same bill and fewer singers had their own bands.
Record companies are going down the tubes as cd sales drop off and brick and mortar record stores are going down like Tower did. I think it will give more control back to the artists rather than them having to conform to what accountants think will boost the bottom line.
