One thing we love about the Portland band Loch Lomond is that, ever since Ritchie Young started it 13 years ago, it has operated as a revolving collective of musicians, depending on who’s available to tour and record. That means that every time they release a new album, they have to update the count. With “Pens from Spain,” out this month on Hush Records, it has grown to a whopping 75 musicians.

“It is really a big, rotating family,” says Young — a fact reflected in the refrain of the title track: “Friends are the new family.”

Pens from Spain is the band’s first US album in five years (although they released Dresses in Europe in 2013). More than any past album, Pens from Spain was a group collaboration, particularly between Young, Jesse Donaldson, and Brooke Parrott. The album’s lush orchestrations reintroduce some of the electronic sounds Young and the gang have played with over the years, ranging from the atmospheric morse code of “From Here to Iceland” to the poppy drum machine beats of “Be Mine & Be Kind.”
