Perhaps a guilty pleasure....

I have no idea why you would call that a guilty pleasure.

I saw Heart  a number of times. At least twice playing bars here in Vancouver and once or twice when they were at their peak. Great hits and two dynamite voices.

Little River Band I saw as the backup band to Nils Lofgren.

LRB absolutely stole the show. Fabulous songs and soaring harmonies that never missed a note.

There is a bit of esoteric snobism on this site and since Heart and LRB were successful and played on commercial radio they may not be esoteric enough to be appreciated.   That said, Jazz and femile vocals make up most of my collection and interest.....but i am not limited to them.

Ignore the disparaging comments of others.  Enjoy your music

I always enjoyed Heart. Saw them once at Winterland in San Francisco opening for Sammy Hagar or something; they had an after-show party at a nearby hotel that I went to and had a nice chat with Ann Wilson. I told her that the cover of 'Dreamboat Annie' sure didn't give much of a clue to what their music was like - I thought they were a folk duo from looking at that! She said they hated that cover, too, but were stuck with it by the record company. 

If I had to make a list of bands that I just couldn't stand, LRB would be in the top 5, but that's just me - if you enjoy them, great!
