I've heard all the bands you've mentioned apart from T-Bell and though I rate all of them I prefer the new Heartland. For a start, Chris Ousey is easily a better and more versatile singer than all the rest. Secondly, there is absolutely no filler on the new Heartland, which I can't say for all of the above bands. Also, I don't hear Ten stretching the envelope(their albums as good as they are are starting to sound samey) whilst the new Heartland in my opinion and other reviewers is probably their best ever and shows some fabulous songwriting. As for the Marvellous 3 I'll have to check it out - their one of the few mainstream bands staying close to their roots playing Cheap Trick influenced power-pop. But their first album definently contained "filler" material though exhibiting much promise! Anyways, check out the new Heartland, it's a winner! Cheers.Kaos Fan!
