Personally, I wouldn’t call the first ten years of M Brecker’s output “crappy”. It’s a matter of the style of the music which we may or may not like. The playing however was always on a high level. It is true that most of his output during the 70’s was in a rock/funk vein and some of it I don’t like, but some of it I do like.
One of the brothers’ earliest higher profile projects was as members of the band “Dreams”. A very influential band that predated “Blood Sweat and Tears” as one of the very first Rock bands to use a horn section and to incorporate elements of Jazz. The horn section, unlike the more popular band “Chicago” was comprised of players that could really play and improvise well.
