I just bought 2 Landreth albums. The first one is called "The Road We're On". Very bluesy and with an apparent Lousiana, or cajun-style feeling. There's also modern bluesrock stuff, as well as the old Delta-blues slide style coming out of Robert Johnson.
The other one is his latest, "Grant Street", and is a live album.
Both are great albums, and lots of good songs. The nod goes to "Grant Street", since I think all good players sound the best live.
What stands out the most is his incredible style, tone and playing. He is THE master of slide, in my book (Derek Trucks is also amazing though). He has a monster tone, with lots of gain, using a strat and some delay. He is complete control, and never sounds like he's showing off. Instead, he is just playing from the heart, expressed in such an eloquent and skillful way most people can only dream about.
Even if few of us can ever get close to Sonny's playing, it is very inspirational to hear him play. It makes me want to practice more slide, and it give me such inspiration and appreciation for playing.
Get "Grant Street", and get blown away by Sonny. Oh, how I wish I could see him live! I hope he comes to Alberta one day.
