Although, keep in mind it's pretty much an indoor drum/bugle corps (some people describe it as a half-time-esqe show) -- so you have to have some kind of interest in brass/percussion performance/music. BLAST is incredibly entertaining with a high degree of talent - and the drummers alone are worth the price of admission.
I've seen it several times now and I've never been bored for a second.
I just saw Blast on Sunday and thoroughly enjoyed it! I agree with Becky, though, I think you should have some interest in this type of genre to enjoy the show. My only complaint with the performance was there were a couple of times when it was "look at what this solo performer can do" show off type stuff - and I thought it was very obnoxious. But other than that, a very different and enjoyable theatrical experience!
i sat in the first row of the touring production, maybe 6 years ago, and enjoyed it BUT i dont think its a 75 minute drive worth it unless you reallllly know what your driving over an hour to see and are excited about it.
