Hi Steve,

The way I see it is that Guitar Tricks is a teaching site and, as such, does an excellent job of teaching a wide variety of playing styles.

In the 'Blues' sections there is also a wide variety of blues styles covered that should give most students sufficient knowledge to play the blues in the most popular styles.

If you want more examples, there is a huge amount available on the web. One of my favourite sites is 'https://chordify.net/. You type in the song you want to hear and play and it comes up with a selection of the song from Youtube and also gives you the chords to play. You can listen to the performance and follow the chords at the same time. Worth checking out I think.

All in all, I think GT has you covered pretty well for aspiring blues players and although it would be nice to see some new blues songs I think GT has you covered pretty well.

Kind regards

Joe
