I was pleased to discover that Classic Rock magazine has started offering a free Daily Download - a daily review and link to free music. They are mostly linking to up and coming bands, for example today's download was from The Steepwater Band - a band I'd never heard of but one that I'm now tempted to get more of.
So far there's been a bit of a mixture of Blues and Rock for download and I hope they are able to keep it going for good we while.
If you want to follow what they are doing, you could bookmark the page for items tagged Track Of The Day or you could subscibed to their RSS feed. Let me know what your favourite free tracks are by leaving a comment on this post.
