The key to a successful jamband is the quality of jams, of course, but also the vibrancy of the rhythm section and the quality of the songs. You get all that with ALO (Animal Liberation Orchestra) and their recent Sounds Like This (Brushfire).
The vocals are strong and the songs stick in the mind. Lebo plays some very nice guitar (but perhaps even more would be even better. That's what live gigs are for I suppose) and the rhythm team gets a head on things.
The Dead and Phish are lurking in the background somewhere, but they only lurk. It's a strong sort of offering and will definitely find adherents and followers in addition to the ones they have already garnered. Nicely done.
